If I could only find a copy of my dyno results, I'd post it here. Needless to say at the rear wheels the dyno said 330 something HP. Stock motor with the original heads worked over and ported along with the intake. I installed 4.56 gears back in the mid '70s and have turned low 13's on regular ole street tires through the chambered exhaust. And the car is very consistent.
When running the car hard(which I don't do much anymore), 7,000 rpms is the shift point and I can tell you in 4th gear at 7 grand the engine is still pushing you back. The vast majority of races I've won over the years was on the last 300 feet of the 1/4 mile....the 302 doesn't know when to quit.
