Are you 2-stepping it down on the line? What does the converter stall. Seems the 1/8mile speed is fast for the ET, what is your 60'. Are you spinning?

Normally 6.0's will get you 112-114.

The 60' looks good. The converter probably stalls more with the added power. May slip more than the 5% I was figuring. Converter seems borderline too loose.

Also the car weighted 200 pounds more last year. What should the converter stall at?

Rick take a look at the link. Tire does make a quarter turn before the car moves. you can only see it in slow motion.

It's hard to say where the stall should be without knowing everything about the engine, but most importantly a dyno sheet. To run quickest it is usually best to have the stall about 500rpm past peak tq, but that depends some on the tq/hp curve and how fast it falls off after peak hp. An overall range of 1200-1500 rpm from stall speed to shift point should be close.
