Danny how did you like the comp cam 20-718-9? I’m considering upgrading to that one from my current comp cam, which is 254/268 - 660/660 -108.
My combo is a 408, 12.25 to 1, Trickflow 190 heads fully ported, 727 5400, 4.30 gears.
I liked the cam.
My combo was 408 11.8 vr200 heads 727 456 gears.
Best pass was a 6.69. My converter was way too tight at 4000.
I now have a 904 with a 600 converter ready to go in.
