Re: '67 Camaro E/SA redo
 

I was under the assumption that when anything breaks in the rear end the trans is usually broke as well or needs to be checked. I bet the shaft got bent when the perches broke and or the driveshaft was rammed into the back of the trans to make the back of the case break like that. I went through two transmission cases last year (350 turbo) both broke in the bell housing. Checked and found the bolts that hold the lower engine mounts to the frame were loose. I also tossed the urethane trans mount in favour for a stock one and never had an issue since. With one solid mount and one stock appreakng mount theres going to be an issue specially if theres a hight difference. Your actually preloading the trans case when you tighten the trans mount bolts to the crossmember. The urethane mount will give a little....not alot. Another problem is with a 46 year old car that cant have any bars towards the front frame there is going to be some twist in the front sub frame. Weakest point...transmission. A rubber mount will allow it to move a bit without trying to twist the transmission in half. As far as the springs go in my opinion the split leafs are the best barr none...i had Tri City Competition springs prior to my Calvert stuff and it was night and day difference. If you are looking for ride height order a set of split monos with negative ride height but keep in mind if they will sag over time. Mine lowered itself enough to take preload out of the bars. Make sure the rear shackles are loose and move free. I have jam nuts on mine to keep them loose enough to move free and tight enough to keep them from deflecting side to side. Hope you can find the trans breaking issue. Nice crossmember too ill be looking into buying one of those.

Re: '67 Camaro E/SA redo
 

CRate... do you run standard type bushing in the shackles? Or Alum?

Re: '67 Camaro E/SA redo
 

Stock replacement. I bought the global west bushing....one fell in and the other was .050 to big. So i sold them to a friend and my mission is to build a set once my lathe is hooked up. Global West did say they would build me a set but after seeing what they sent its a simple project for anyone with some basic machine shop experience.

Re: '67 Camaro E/SA redo
 

I wouldnt put much effort in it...anything that fits the holes will be fine. The only thing that moves on mine are the thick side plates. I used slightly longer bolts and nyloc nuts to secure but not tighten the plates against the bushings...swings freely.

Re: '67 Camaro E/SA redo
 

FYI the solid rear shackle bushing are a good idea they will stop any lateral movement and operate super smooth. Im constantly looking for a grease that will live and not move away from the bushing. I service the spings once every 3 races just to make sure that shackle is moving free and not bound up. I just had it all appart and tried ARP fastener lube on it. I was able to tighten the bolts all the way and the shackle still moved smooth. After a few hits at the track we will see if its still happy.

Re: '67 Camaro E/SA redo
 

I agree. I use old 3/8 polly locks on the top and a jam nut on the bottom with factory replacement shackles and bolts...LOL. works fine i think

Re: '67 Camaro E/SA redo
 

My way I don't have to worry with grease at all. Not to concerned with a little slop as this car only goes in a straight line...I hope hehe. :p I think those using a factory side plate with the welded thru bolt have more issues. Mine are seperate plates and bolts.

Landrum 150# monos...hope these are the last say.

Re: '67 Camaro E/SA redo
 

Rich,

Did you have any problem installing the cross member and did it seal lighter or heavier than the stock one? Thanks

Re: '67 Camaro E/SA redo
 

New crossmember slipped right in...it is lighter being tubular, but the shift cable interference was not improved. I ended up adding some spacers between the shift cable bracket and the pan. The end of the cable that connects to the shift arm is at a slight angle...best I can do with it for now.

I ended up swapping springs this evening instead of going to the track with the stock mono's. I felt like the housing might try to move without a locating pin on both sides of the leaf. The 150# Landrums feel just a tad stiffer than the stockers, but still good. I'm guessing the stock leafs are rated around 125#. I did have to use one lowering block to get the ride height down...it's just a little higher atm and it may settle a little after some use. Will try to get to a track tm evening to try it out.

Re: '67 Camaro E/SA redo
 

Went to the track today hoping for some good results...a mixed bag at best. The good news is I did not break anything and I did not require the use of the winch to load the car hehe.

The car repeatedly shucked out 1.50 60' times and ran 7.26's back to back. The car is leaving like the old Mopar's used to...straight out with barely any front-end upward motion. I believe I am now battling some type of carb issue as it just doesnt hit the tires hard like it once did. Don't believe it has anything to do with the spring or shock changes. The GoPro video shows nothing of real interest that I can pick out.

http://youtu.be/IrUygg4rWzY

I had another camera pointing at the pinion, but the angle was ineffective rendering the video pretty much useless. From the above video it appears to get some pretty good rotation tho. I'll have to fashion a bracket to get the camera more in front and level with the yoke.

http://youtu.be/XpB8IT_gih0

With only one lowering block installed the ride height is slightly higher than previous...figured I would let it ride for a bit to see if the new springs settle any.

http://i434.photobucket.com/albums/q...psd79298a6.jpg

Here are the old motor mounts I pulled out of the car. There was almost a 1/2" difference in height between the two...likely the culprit for the cracked cases.

http://i434.photobucket.com/albums/q...psab761f10.jpg

http://i434.photobucket.com/albums/q...ps38cc829a.jpg

I will keep at it until I find the bug.

Re: '67 Camaro E/SA redo
 

Good luck on getting your car dialed in Rich. I hope your breakage issues are over and it is just fine tuning the combination.

Re: '67 Camaro E/SA redo
 

What is your converter flashing to? its either the carb or the converter... didnt you do some 1.45's before?

Re: '67 Camaro E/SA redo
 

I did not look at the tach yesterday...probably should have. If it turns out to be the convertor I may have to re-think this automatic deal.

Re: '67 Camaro E/SA redo
 

Sounds like it is too tight... you could always try different carb, to see if that is it... My $ is on the converter... didnt look like it spun any...
What brand are you using? The videos from your prior testing, looked pretty good...but you have changed converter since then, correct? Too bad you dont have a 350 turbo in there...probably easier to find a converter to swap in ... Atleast you made it down the track... I dropped heads off today...My new cam should be coming in , early this week...

Re: '67 Camaro E/SA redo
 

Nope...same ATI convertor.

Re: '67 Camaro E/SA redo
 

put a 1/4'' stroker in it...nobody will ever know...hehe

Re: '67 Camaro E/SA redo
 

Just got some enlightening info that was not provided earlier. I asked for some video of the car leaving, but none were taken...I was also not told that there was excessive body separation at the hit. Now that I have this tidbit of information it explains the results and the needed remedy...I'll put the adjustable shocks back on the car and crank up the extension as they were during the 1.45 60' outing. I really must figure out a way to self-video what the car is doing at launch...perhaps a suction cup mount for the camera just forward of the quarter panel. After this minor glitch I probably won't need it again tho. Car goes back to Bowling Green the 18th...hoping all this drama has come to an end.

Re: '67 Camaro E/SA redo
 

Hey Rich, I saw a while back that the Fazio family posted video of their SS/L Mustang launching to get advice about the launch and the suspension movement between gear shifts. They mounted the camera under the back of the car and got it so both shocks could be seen. Then made a pass. They had an answer about the issue real soon from this website. Just suggesting camera location may be more helpful than putting it on the body. I may also be completely out of order too. Just trying to help Sir.
Good luck with this way cool Camaro.
Walt

Re: '67 Camaro E/SA redo
 

Thanks Walt - I had very good footage of the suspension...it's just that it was the very first time I had seen the car from that vantage point and it didnt immediately click what was happening. I had already made the decision to swap the shocks before finding out about the body separation. At any rate the next outing I will have video from both under the car and exterior.

Even with the less than ideal set-up you could actually dial/race it as it was. Back to back runs in the heat with poor air and I short shifted the final pass...

Re: '67 Camaro E/SA redo
 

Rich, how did things go today? -Al

Re: '67 Camaro E/SA redo
 

Well, let's see...I flubbed both time trials, had no clue for first round and went red for a SS/BA 9.teens opponent lol. How was your day?

http://i434.photobucket.com/albums/q...ps3778801a.jpg

I've just about pegged this on the convertor going south. How else does a car go from 1.45 60' to this? Funny thing is it is consistently bad and the et's get quicker. It sure is messing with my lights. The car just doesnt have that "snap" any longer at launch...we are going to do a convertor swap to confirm. Thinking maybe the convertor is tightening up, slipping less resulting in the decrease in et and more mph???

Re: '67 Camaro E/SA redo
 

Only thing I see is the convertor just doesnt flash...like it's just driving off the line. If anyone can point anything else out be glad for the input.

http://youtu.be/8x73mClCbRk

Re: '67 Camaro E/SA redo
 

Just got the word this morning the convertor is good. Had it cut open and no problems were found...they will loosen it up a little more before putting it back together.

So...the transmission must be slipping. Partner says the fluid smelled burnt when he pulled the convertor out...will just have to take it back to Thomas I guess.

Re: '67 Camaro E/SA redo
 

Rich,

How fast did you go with the old slapper bar set-up ??? That's where I would start to look, something isn't right ?? Just my two cents, worth checking out ... You can check the tranny & I hope that's the problem, but if it's not ???? Good Luck, keep us updated .?

Re: '67 Camaro E/SA redo
 

It was only going 7.40's with 1.50 60' when it still had the Powerglide and Caltracs.. It did 7.19 with a 1.45 60' with the metric 200 and Caltracs. We never really ran the car ourselves with the old slapper bars. Since we got the trans back it has never had a 60' better than 1.52...thus the reason for us to suspect the convertor. I really can't see it being anywhere else other than the transmission since the convertor has been opened and verified good.

1.54 60' on this pass... http://youtu.be/8x73mClCbRk

Re: '67 Camaro E/SA redo
 

Rich you have a PM.

Re: '67 Camaro E/SA redo
 

how much did the metric200 pick yours up thanks

Re: '67 Camaro E/SA redo
 

That would be hard to guesstimate in our case. The car originally had a Powerglide in it so the difference was drastic. I'm told the gain from a metric vs a good running TH350 combo would be at least a tenth.

Re: '67 Camaro E/SA redo
 

Put a proven TH350/convertor in this afternoon from a H/SA Camaro donor. It should reveal if we are fighting a trans problem or not. I will also be taking the split-monos with me to the track Friday and will swap them out there if I feel there is a need. Fact finding mission will be revealed hopefully.

Re: '67 Camaro E/SA redo
 

Rich, using a proven trans/convertor is a smart move. While it may not be the ultimate for your combo, it will eliminate a lot of variables and answer some questions. Looking forward to hearing your results. Hang in there, man....... :) -Al

Re: '67 Camaro E/SA redo
 

Surprising results today Alan. Had it not been a uncommon bog the first pass it may have gone undiscovered even longer. There is something going on with the Q-Jet on the car and I'm not entirely sure what it is...I do know it is at the launch. Came back to the pits and put a new accell. pump in it and the next pass was marginally better. Came back and swapped carbs from my buddy's H/SA car...it jerked the wheels that pass, but fell off on the big end. Mine sucks at launch and runs great on top...his is just the opposite. We both need carb majic it seems.

I'm convinced now there is nothing wrong with the metric 200 or the convertor. Going to have a pro look at this carb and see what it needs so we can get back to racing instead of wrenching. ;)

Re: '67 Camaro E/SA redo
 

Good to hear. Carbs are so much easier to swap than trans/convertors. :cool:
Dean Oliver really knows his way around these carbs, Rich. -Al

Re: '67 Camaro E/SA redo
 

At the risk of sounding obvious, check the choke pull-off on your carb to see if it holds vacuum and how long it takes to release (should be about a second). Also, maybe try another float and make sure the secondary flapper tension hasn't loosened up ( screw loose). Ron.

Re: '67 Camaro E/SA redo
 

There wasnt anything obvious...the carb still runs like gangbusters on top. I have the metric/convertor back in the car now just waiting on the carb(s) to come back from KY.

Here is a timeslip from the previous weekend...you can see where the problem is from the sixty foot time. The carb is working great on top.

Re: '67 Camaro E/SA redo
 

Do you know for sure that its not dumping a little gas , from secondary rods into the rear flaps? I have a great source for parts... Cliff Ruggles, at Cliff's High Performance 740-397-2921 He sells the best parts, and know's how to make them run, as well.... He is in Mt Vernon , Ohio...Tell him Brent sent you...:D

He also sells adjustable choke pulloff's...they are the bomb... the only way to go...

What primary jets? Rear rods? My car has .065 primaries and .044 sec rods, with long tips( DA i believe) and it ran 10.81/122 on 462... and it ran
7.33 on a spinning 1st pass , at 88( out of the gas) in the 1/8 mile... with a 1.53(spinning 60ft)

Re: '67 Camaro E/SA redo
 

This is the original carb that came with the car Brent. Has always run well until recently. A pro in Bowling Green KY has it and another carb atm...I'm sure he will find the problem. The original carb came with 68's in the primary (no rods and has never been touched). Secondary rods have seen AX down to the current DP without affecting 60' times. Ironically the car has gotten quicker even with the sorry launches...it must like those leaner rods with the current weather conditions because it runs like gangbusters on the big end.

Re: '67 Camaro E/SA redo
 

WIsh you lived closer...we'd try my carb on it... I'd be surpised if you didnt get right back in the mid 1.40s again... Get that carb right, and i bet you pick up .2 at the 1/4...maybe even more... Man, i cant wait to get mine back together... Waiting on cam and lifters to come back from coating, and gaskets should be here tomorrow... then, degree cam, check a couple clearances, and slam it back together... hehe... I have break in springs on, due to new cam/lifters. Had Chris at Comp do me up another grind( little less aggressive) , but i believe may have been an exhaust guide that was a hair tight, that caused my issue...ran every other scenario , and thats the only one that makes sense...

YOu running / testing this weekend?

Re: '67 Camaro E/SA redo
 

No test this weekend...havent got the carbs back yet. I did enter the NHRA Hot Rod Reunion today that is scheduled to run June 12-14 at Beech Bend. Going to run the car in Modified Eliminator in the 11.00 or 11.50 Index depending on what we have ready to go with.

My partner has been wanting to pull the 327 out of his Chevy II and replace it with a more docile powerplant. He really wants to see what the beast 327 will do at the track and this would be an excellent opportunity to swap it over to the Camaro. I would guesstimate it to be around 500hp...should run in the 10's I would say. I'll take the car regardless of which motor we run tho.
