Well, crap. Don't have any pics to speak of but the Baby Gators was pretty much a disaster. I did manage to get qualified and run under the index, but that's where my luck ran out. It appears that after the heads and intake were surfaced, it moved the distributor too low onto the oil pump and was bound up. Over time it shifted the timing and kept slowing the car down. It had maybe only 28* or so by the time I ran first round and I had no idea. I could only go 13.13 first round. Drove all day back home Saturday and took it testing Sunday to sort out the issue. Timing was one of the first thing I checked and realized it was extremely low. After reaching out to a few people I realized what was causing the issue, I tightened the distributor back down and added a few extra gaskets and it went right back to printing tickets. In 3 runs at Shadyside on Sunday it moved .007 to 60ft and ran 8.00 and 8.02 on the two runs I ran it to the finish line. Dang this has been frustrating but I'm working on it.

I have pulled the plug on the Gator nats and withdrawn. I just can't afford to take my stuff back down there again this week, and so far, the state hasn't been terribly good to me. I'm going to go to my local bracket track and footfeed the stocker to get some more seat-time and continue improving the car. I'll be back to class racing at SGMP in a few weeks, looking forward to it already.

I learned a ton while down in Gainesville this weekend. I got a lot of help and advice from Tim Stickles who helped me go through my Q-jet and show me what did what and how to adjust/change/tune it better in the future. He even loaned me a different hanger and some secondary rods to try. Super awesome guy in person and extremely generous with knowledge and parts. I hate the adversity he faced as his SS car kicked the rods and his stocker was having consistency issues along with mine.

I noticed your PVC valve plumbing. I believe its preferred to have it pull vacuum at the carb base. The way it appears you have it , it is possible for it to lean the mixture only on one or two cylinders. At the carb base it will be more evenly distributed. Might show up more at idle. It's a vacuum leak. Of course your results may vary. Good luck 🙂

My carb is not fitted with a vacuum tube at the base right now. I'll look into it when I pull it off again to see if I can see where one is meant to be and re-plumb it if possible.

I did not really come close to winning this race, BUT I FINALLY GOT SOME ELECTRICITY IN MY LANE! Made it to 10 cars on Sunday for by far my best appearance with a long roof. A huge thank you to all the people who have helped me with this car, turns out it’s pretty good when it doesn’t break! Qualified in the #37 position out of 40 cars with a -.19 under run. Once the weather swung, I dialed about -.30 under, so I'm still comfortably in and race-able. Had an unfortunate break-out when the car picked up a few numbers through the middle third round, but not a bad showing at all and I was making the right decision at the stripe, just didn't do enough quitting.

I think you're right, which is bad because I'm about to run out of excuses! Check out these two time runs and first round the week prior to SGMP where I went bracket racing for some extra seat time! It wasn't quite this good at SGMP, but it wasn't bad either.

That last stretch of I-85 coming home from Valdosta really did a number on my car. Looks like it was rough enough to blow both front shocks out :/

Guess this is what you get when you race a really old car with stock components. I'll throw this in the same broken parts bin as the rear wheel cylinders that blew out on the first test drive.

Finally showed my old bracket car some love last weekend. Bolted some small tires on it for a little Thursday night TnT and grudge, then the big tires for some bracket action and throttle stop testing. Getting geared up for the Charlotte 4-wide where I'll be running Stock and SST!

Shoutout to Marion Stephenson for selling me some used Phoenix 14.5x32 radial construction big tires off his Comp car, I think the my car really likes them.

Out with more old, in with more new! The front shocks on my wagon had completely blown out and were leaking all over the place. I snagged some new 90/10s off the internet and tossed them in the car last night before the next D2 double this weekend in Reynolds, Ga.

On another note, managed to collect some coin at the first SGAS race of the season scoring a runner-up finish to the great Jim Perry at Carolina Dragway last weekend. Driver was on it most of the day including the final, but a .013 pick up to 60ft was my demise as I couldn't get back to the good and lost a double breakout 6.298 to a 6.299. Good race and a nice payday, basically covering all the upgrades I did to the car over the winter. If you live down south and have at least one testicle, (outside of Lauren Freer and Michelle Lisenby, y'all are cool of course) come run one of these SGAS races! They are a great time and deserving of a bigger spotlight!

Re: JP1738's Stocker and S/G car
 
NEVER SAY DIE. After a nearly complete bust at zMAX DRAGWAY with my stocker and mazda in S/ST, coming up short to Christopher Webb and Eddie Longhany Jr., I decided the only way to make something of the weekend was to keep up the pace and persevere. I left zMax at 11pm saturday night to try my hand at the 6.0 and Pro Tree Door Slammers classes at Rockingham Dragway for their Civil Wars race. Pulled in Sunday morning, got one clean up run, and went to work. Doubled in both classes to 4th round where I turned it a few thousandths red to Steve Sechler (the eventual winner) but I kept it together for the win in 6.0! What a fantastic event they put on and a very much needed confidence boost and payday for me.
Thank you Daren Poole-Adams for helping me get my stocker to and from the track, I really appreciate it.
Thanks again to Brad Plourd for the tires I’m ruining on my stocker. They just keep working and I’m still so greatful for that. Also shoutout to Scot LaMar for his transmission I’m still abusing.
Congrats Don Shuford on your fat dub at Charlotte, I had you picked to win on my fantasy team.
Thanks Meg for the pics and support, your patience is appreciated when I’m all to hell.
Also awesome to see my good friends at the track Glenn Mcconnell and David Lester. I literally could not have done it without them. The coil wire on my car burnt up, but thankfully I had a spare coil and David loaned me another wire to make it happen. It all got ziptied to the cowl and away I went. Glenn let me borrow some power after my generator quit and a couple hotdogs to keep me from falling out. Thanks guys it was great hanging out. I’m so sorry for the parts attrition on both your cars. Let me know if there’s anything I can do to help.

Re: JP1738's Stocker and S/G car
 
Managed to snag another win at my little local outlaw track Shadyside Dragway! Picked up the 6.0 index win! The pro tree has been very good to me so far this year. I've entered 4 P/T races this year, SGAS at Carolina, 6.0 at Rockingham and Shadyside, and S/ST at Charlotte and have made 3 finals despite my early exit at the zMax National.

Five rounds of racing, tough competition, and a whole lot of nitrous to get it done! No barometer this past weekend meant we were spraying from the water box the the E/T shack, but I had enough to get the job done in the finals!

I brought my stocker along with my new to me double open trailer and had a good friend of mine wheel it. He's a lot more experienced than me at swapping feet, so I wanted to get him in it to try to win some rounds and give me feedback on what he likes about the car, doesn't like, and changes that might make me more competitive. He wasn't able to go deep in the race, but we did learn some very valuable information about the set up and things to note moving forward. It needs another oil change and the shift points adjusted still, but it gets a little bit better every time it shows up at the track! If this had been an NHRA race, we would have struggled to get under the index, we were only managing around an 8.22 off its 8.26 index. Safe to say it does not like thin air! Barometer was sat around 28.85 in/Hg most of the weekend.

Re: JP1738's Stocker and S/G car
 
Got my shift point dialed in best I can!

The car started out with a #2 weight+orange spring and stock weight+green spring, which shifted at 6750 rpm.

Then tried to make a big swing to see where that put me, left the stock weight side alone and changed the #2 weight to a #1+purple spring (heaviest spring and weight) to see how much that would change the shift point. It made a huge difference and moved the shift down to 5500 rpm.

It seems counter intuitive but a stiffer spring quickens the shift point, I decided to leave the weight alone this time and go to the lightest spring. #1 weight+red spring. That got me right where I wanted to be at 6200 on the button. In the future I may try a slightly stiffer spring, maybe one step up to bring the shift in just a touch sooner, but I think that's good for now.

Final combo for any who might reference this later:
stock weight+green spring and #1 weight+red spring got me 6200rpm.

Sorry to all my neighbors who heard me making test passes at 11pm Tuesday while testing the shifts. Can only test it at WOT...
Also shoutout to the guy who saw me testing again Thursday who yelled "DO A BURNOUT" which I promptly did. I couldn't resist.

*All testing was done in a closed environment and all safety measures were taken (helmet and seatbelts utilized)

I'll include an image of the weight and spring chart for everyone's reference.

Re: JP1738's Stocker and S/G car
 
It's been a very busy beginning to summer and I haven't updated my build thread in a while. Mainly because I haven't made many changes or broken anything in the last month thankfully. Since last updating I attended my first CCRA race at Rockingham dragway, entered a few more 6.00 Index races, and made my way to GALOT for the Sunday 1/8th mile national open for Stock and Super Gas. Haven't made much noise at all with the stocker in it's two appearances since I last posted, but not for lack of effort. An .036 r/t dead 9 pass at The Rock was not good enough to get out of first round and an .029 2 above lick did not get it done first round in stock at GALOT either. Pulling in the lanes rather poorly but I'm thrilled with my improvements at swapping feet and the car's consistency since I fixed the 1-2 auto shift.

My Mazda has been absolutely on fire this year, however. I've entered 5 6.0 index races this year and 1 SGAS race and made it to the finals in 5 out of 6 of them (and should've gone deeper in the 1 race I didn't make it to the final in, met the tree coming on 3rd round after letting go stellar all day up to that point). Wasn't able to capitalize on the car's hot streak at Charlotte national or GALOT though, .016 take .004 at charlotte no good, and .012 6.297 at GALOT did not make it by first round at either race.

Funny how you can remember the losing rounds with great detail but the winning ones not so much. Anyway, here's a few pics from the last month as I've stayed busy racing!

Have you ever compared aluminum and cast iron intakes on your stocker to see if there's any difference. Most everone I've talked to says Iron is faster but it's still hard to resist running something that's 20 lb's lighter on front end.

I haven't tried the cast iron intake manifold, but I'd like to. I run the weighted class for my car, N instead of M, so I don't really care about the weight. I can peel 20 pounds out of the weight box fairly easily.

. Bill I tried two on the dyno at Trumble shop both were 5 to 7 hp less than the iron.

Re: JP1738's Stocker and S/G car
 
Welp, looks like the stocker is going to be down for a while. Killed a new to me set of tires and completely sheared off an adjustable 4-link bar. I'm thankful the car stayed rubber side down and that I didn't blow a tire or lose the entire rear-end. Not sure when the bar broke, on the first pass or on the trailer on the way to Wilksboro Dragway. Either way my wagon is down for the count. I'll get it fixed and back going straight again before too long!

It's pretty much destroyed. I have no hard data/evidence, but when I press my finger into the undamaged portion of the tire, there is a substantial amount of rigidity. When I press into the portion of the tire that rubbed, its like pressing a balloon animal.

When I get back to my shop again I'll snag a pic of the tire off the car, it's paper thin where it wore on the frame rail.

May i suggest to look at the junction of the axle tube to the center section of your housing. You could find welds broken there which could also explain why your car lift the front driver side higher than the passenger side.

The plan right now is to replace both 4-link double adjusters on both upper bars and completely re-setup the 4 link to a true neutral setting. That way I can rule out any binding or pos/neg preload that might have been introduced in the car. I will also check the housing, 4-link brackets, and torque-boxes for any warping or damage. Right now I'm on hold with all my cars because my main workhorse (my mazda) needs work desperately and the transmission in my truck welded all of it's forward clutched together. Even if I had a raceable car (0 for 2 right now), I have no way to get either of them to the race track for the next few weeks.

Back in action! 2 tons of fun coming to a class race near you! Got two brand new double adjusters installed on the wagon this week. Did my best to set it up just like it came out. Thanks to Tim Stickles for the quick phone call helping me get it set back up. It ain't fast, but 3600#s is a whole lot of steel to get rolling! Next week I'll get some new tires mounted up for it as the ones on it now are destroyed from the broken four-link bar.

These double adjuster have a lot of thread engagement, they are the same length as the adjuster that came out (5 inches). I set the bars up to be the same length they were before, and you can see the markings of there the old jam nuts were on the broken adjusters. there is that much thread engagement on the new ones as well. It looks like a lot less, mostly because the adjuster nut on the new adjusters is much shorter than the old ones. It appears to have less engagement, but its has at least an inch of engagement on each end.

Re: JP1738's Stocker and S/G car
 
Get you a man who can do both! Class racing one weekend, outlaw small tire N/T the next! I'm headed to Pageland Dragway in Pageland, SC this weekend for a 5.90 index N/T shootout only for cars on 28/10.5s or smaller. Going to be a great time and should pay some good money! No buy-backs, no round money, winner take all! Picked up these used MT 28/10.5 slicks from a guy near Wilkesboro last week and got them mounted up on my beadlocks. Did a quick garage burnout to lose some of the feathering the tires had from the no preps the guy had run them in before I bought them.

I have to say, these tires and the compound they use for them are incredible. So much stick and grip they literally pulled up some of the concrete on the floor of the shop. If you've ever wondered how No-Prep tracks come around so fast, this is how. These tires are complete black magic and I would venture to say could hook on just about anything. Wish me luck!

Years ago at another house I built a 32x28 garage. As soon as it was up tight and all the inspections were done, I rolled my mustang in and did a burnout to "break in the new shop".
New concrete got hot and exploded a fist size hole in the 2 week old concrete that I paid $5000 to have laid. The wife was furious but I said, "now it's mine".

Had that place 364 days and was posted to another province....didn't affect the resale, lol!
