Did you install longer valves in teh heads? I seem to remember the max lift being .680 on the streets.

What was your mph?

Need the actual weight of the car, but assuming about 3000# it would be in the 600-650 range to run those times.

Bruno said he had a heavy car.

Anyone know what it is and what it weighs?

Damn you guys think 3500lb is heavy. My coupe will weigh in at around 4000lb :shock:

Your probably in the 650-700ish Range, also alot depends on your chassis set up and how well everything is working together. the Calculators are only Approximate.
