I have been working on this 283 /66 chevy II for about 2 years as money will allow. I have a 198 low gear p/g along with a 587 gear and a 26" tire for 1/8 and 28" for 1/4 mile. My converter will only flat stall @ 2800 to 3000 and wants to push at that. It has no flash unless it is dropped down to around 2500. I know from experience from my wagon stocker it should be a whole lot looser.I shift @ 6400 and the rpm's drop backt to 4200 and the engine acts like it just went on a throttle -stop.I know the gear is to low ,but without it the car will not get out of its own way. I tried a 538 and it killed it .I talked to ATI while i was in Charlotte @ E-Max National. They sent me one and this is doing the same as i already had, maybe about 200 rpm looser on the flat stall.I am thinking of sending it back and ask them to loosen about 1000 rpm's.If this works i then plan on a 557 gear .Car is 3040lbs. It has a 164-165 60 foot and runs almost 85 mph in 1/8. It only ran 7.93 this weekend .It was consistent as it won 2 rounds in a $5000.00 electronic or box class this weekend before going red in 3rd round with my son driving.He was .011 on tree both winning rounds and was .019 red 3rd round. Any ideas out there.

Have you had the transmission checked? It almost sounds like the stator is loose. That's rarely, if ever, a problem in a low HP car, it's seen a lot in the big HP Super class cars. But it is possible.

Before we get into the converter, how about this.
Seeing you run mostly 1/8th mile, how about a 6.14 gear? What does it go thru at?

Marc, I was comparing this whole deal to my old old Belair wagon. I ran a 614 in it and all i did was change tires for 1/4 to1/8.When i sold the wagon , Mark Lewis helped the new owner with it ,. They actually replaced the gear with a 557 thinking it would help the 1/4 and hurt the 1/8. Instead it helped both.That car went 1.43 under in Rockingham the same time Lee Tuttle went 1.63 under. I have since bought that motor back and is no were close to those figures. I am lucky to run 25 to 30 under.I now have a new engine that Mark has built for me. I know it will be faster because he built a new engine to replace the old one i bought out of the ol wagon and it was at least 3 to 4 tenths faster in the wagon.I 'm just struggling to get the right combo.The converter in the wagon would foot stall up to 4500. That is why i think this is the problem. I was hoping someone out there has maybe gone through this and kinda shorten my process of elimination. Keep suggestions coming , maybe i will get lucky and stumble on a solution. If there was a problem with the tranny ,would i be able to check something or listen for some sort of noise. ?

Jery , I would be more than happy to put a 3 speed in that ol baby. I have been pushing for that very thing in IHRA. You would think after being in tech for over 10 years i would have a little pull.<NOT>lol!!@#!%#@

Danny, I talked to Billy and his falls back to 4900 rpm on the gear change. I would think you would need a 4800 converter.

Danny, give coan a call about your problem, you won't regret it. Just saw your in lagrange, nc. I use to live in the smithfield/selma area just off i-95 and ran a 1966 chev ii (327-350 hp) out of smithfield repair service. Now that was fun times
except for having to run that "cartel" out of clinton/fayetteville area. Seriously, give coan a call, they've been very helpful for me, and i'm setting on the rio grand with 100 plus degrees in the summer time(and that's in the shade). |
