Timing curve for my big-cam 451?

DrCharles said

Well, I didn't want to deviate too far from the design parameters. I can always change the installed centerline later. The Direct Connection catalog listed the powerband as 3400-7000, presumably for a 440, so a hair lower for my 451.

Any thoughts on the timing? :poke:

You already did that because your static compression is too low for that camshaft. That's deviation, right there and calls for deviation elsewhere to get it "right". [email protected] needs every bit of 12:1 to run to its full potential, so it needs more camshaft advance to help get cylinder pressure up. The 2* advance they give on the cam card takes for granted that you have the "correct" static compression to run that cam. You do not, so you have to "make up" for it elsewhere.
