We had a friend that did up a '69 RR with a .509 cam, big single plane intake, 906 heads, 833 four speed and 4:10 gears at the same time I built my 440 with .528 solid, stock intake, stock 452 heads and 2500 stall t-flite with 3.23 gears in a '71 Cuda. Mine was basically a 9.5:1 re-ring and bearing job with a mild cam.
I talked with him a few months later at a show and broung it up since I'd been to the track and knew he had too. He was not happy and mumbled that it ran mid 15's. My car ran
13.57@104. I fully expected him to beat the snot out of my car with his combo!
I think alot of people overlook small things.
Things like re-curving stock distributors and making sure they are working properly in the first place.
Things like degreeing in the cam. I can tell you my .528 was installed with a Cloyes true roller and was 8 degrees retarded when I checked it with the "dots just lined up." I have no doubt my car would've run 15's if I hadn't checked the cam.
