"Cliff,
How much stall on the converter?" I have the old reliable "Jim Hand" 10" unit. Mine flashes to right to 3400-3500rpm's on a hard run with traction. This is just a tad higher than most folks see, but every converter I've had in this car, even the 13" unit flashed pretty high. Might be because of how hard my engines "hit" the converter, the tune on them is pretty decent, and they are built to make a TON of low end power, with super-quick throttle response right off idle, etc. It's amazing how well these Continental converters are "locked-up" on top end. I go thru just past 5000rpms at over 120mph, which on the calculator shows very little slippage at all. Most converters of this type will show 400-600rpms slippage on top end, some even more. Mine is less than 150rpm slippage when I do the math on it.......Cliff

New Best still with 3.08 gears
Consider me "old fashioned", but the brain still has a hard time understanding these ET's and MPH with the rear gear ratio advertised! What horsepower would you have to have with 3.08's and the ET's listed??

Torque is really what does the job!Its really the head cam package by SD performance..that gets the credit..I've done a few tweaks but could still have a better setup,my heads are still 85 cc's,non ported torker 2 intake,machine shop 462 with cast rods and heavy TRW pistons!I'm also still not satisfied with the carb tune and settled on the ignition curve.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
