Great thread Sledgie!

Most of these combo's have fairly small cams and I've been told by several racers that 440-1 heads seem to really like a smaller cam unless you are running alot of compression and RPM's.

My car is 3200#'s with me in it, compression is somewhere between 11to1 and 12to1 , shift at 6600, trap at 6900, 4.30 gears with 29.5x10.5 tire.

My cam is a Cammotion roller 706/661 lift with my 1.5 rockers, 281/283 at .050, on a 104.

Last summer I had it installed at 106, everyone said that was wrong, that cam needs to be advanced. I put it in at 102 this summer and the car slowed down.
It has alot of overlap I'm told, and my cranking compression is only 150.

The car goes easy 9.90's in bad air and .80's in good air but I think a smaller custom cam will actually make my car quicker.


On the other hand, RonP's 440-1 motor runs real strong with a big cam. But his compression is up there some.
