472, powerglide, ladder bars,tryed a 5000 stall convertor and 5800. Tire pressure is 7psi. Tryed leavin at 3000, 4000, 4800 and 5000 with very little change. Once the car is in high gear its on. Looking for suggestions. Thanks. Birdtracker

What rpm r u leaving off the t-brake. Seems flat.

What shocks... it does seem very flat like the
power isnt there.. whats your timing at

timing is 36, distrubutor is locked. I tryed leaving from an idle, 3000, 4000, 4,800 and 5000. something is amiss thanks. Birdtracker

Looks to me like it's dead hooking and bogging it down.

It just looks like the motor is numb at the hit.
What are the 60' times anyway?
ET & speed?

Timing, jetting, float level, cam size, low gear ratio, etc...... Could be any of those things or more.

Converter way too tight

I had a 5,000 stall convertor in it, and put a 5800 and the 60 foot didn't change. 1.65. Will run very consistant 6.55s in the 1/8 at 119. Plan on going to Norwalk just to experiment. Birdtracker

What motor/cam/carb?

472, 690 Comp roller, and 1050 Dominator. I started with 92 squared jets and went to 97. Back to 93 front and 94 rears. I have not tryed a different carb. It starts great when cold, 2 pumps and fires right up, when hot it takes awhile of cranking but starts. Birdtracker

Mph looks high for the time. Looks like the cam is retarded. Converter to tight. What gear? How tall a tire? When does it go into high? 472, wedge or Hemi? 3.90 or 4.15 crank? If Hemi that could be your problem, needs more gear. All a guess until more info.

wedge 3.92, 14X32 and 4:10s. Birdtracker

It looks to me like the sprag in the converter may be wounded, no torque multiplication.

4.10 is a low gear to work with a glide. 4.56 would be much better for a mid to high 9 second car.

could trans low gear clutches gone away,,

Needs 4.88s

Minimum, could go 5.12 if just running eights. You don't have the hp to run 4.10s

Two things come to mind on this, is the shifter adjusted so it is in first only? The second thing is the reaction shaft is loose in the converter from the front pump. My car had that happen last year and again this weekend, I think The car lost a bunch of ET and MPH all of a sudden after stumbling on the line and looseing a bunch of 60 ft
Let us know what you find, I've seen several cars leave like that when the shifter cable wasn't adjusted so the pin on the cable would slide in and out of the shifter arm in first gear, the shifter arm would move a little bit when you pulled the cable end pin out of the arm I've seen the same thing on torqueflytes, there leaving in two gears, not worth a hoot

Needs 4.88's and a custom converter. Ever dynoed the engine and optimized the tune?

32" tire, powerglide...that thing needs a lot more gear than 4.10. We've run up to a 5.43 gear in the Camaro w/ a 29.5x10.5 tire and a 1.76 glide. Just running 1/8 mile though.
I agree w/ the others and use a 4.88.
