Well I have waited 6 years to fire this thing and its finally alive. My question is I cant set my inital timing at 12 deg. If I do its way to slow on taking the gas. What should the total timing be? My motor is a .030 460 with trw2443 pistons ported dove heads with 2.25 intake and 1.75 exhaust valves, solid roller cam I think the duration is .292 and the lift is .631, victor intake with a 1050 dommy on it.

Keep bumping it up 'til it runs like it's supposed to.

Its at 18-20 deg now and I like it there. It seems like a lot. This is my first 460 build. I have built many small blocks and 12-14 is where they liked it.

Bigger than stock cams want more initial timing. Not so much a big-small block thing really.

If it's at 18-20 now just make sure your total timing isn't to high.My engine runs the best with 20-22 degrees initial and 34-36 degrees total.

Later Mark.
