Where does it feel like it peaks the horsepower? Wanting to stay flat tappet or wanting to switch to a roller? Have power brakes?
no power brakes.it got up on the rev limiter at 7000 in a burnout.not sure where it peaks,but it hit 7000 . i got my weight at a local scrap yard.it could have been wrong but i parked on the scales and got out of the car.i have fiberglass hood and fenders no cage,alu heads,intake,water pump,no console,no tools in car,no back seat.scales could have been off a little,recycle place are ripoffs,maybe there scales are set low,i dont know but im not going to argue over it without knowing for sure.
OK your car is in the Gonkulator, which is not as much fun nor as definitive as a timeslip, but its free anyway and no broken parts.

I start with an all-iron Fairlane at 3550, an all-iron Comet at 3580, full of gas, spare, jack. But that's a lot of weight you took out.
I guessed the car weight at 3200-3250, call it 3400 down the track.

That's shifting at 5800. Shifting the Gonkulator at 6000 gave the same.
I kinda agree w Brent, not sure how much more you can do with a hydraulic cam.
Retarding this cam 4 degrees to straight up lost 6 ftlb and gained 3hp, not worth it.

I assumed 3" exhaust. Running open headers, like the GOOD old days at the Dirty "D", Gonked to

Not much gain but it sure sounds good.
The main reason I think for open headers today, beyond the free educational experience in American History you are providing for society, is it lets you tune collectors. I'm not sure what headers you have, I guessed the FPA's that Jay used in most of his TGFEIC dyno runs. Those don't seem real sensitive to collector length with your engine, but again that's an easy thing to try.

Well that's 3 tenths quicker without even changing the cam. Have you had it to the strip yet? (Good place to weigh it too, they have to be pretty accurate)
