Keep bumping it up 'til it runs like it's supposed to.
Fired new motor have some questions
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.

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.Keep bumping it up 'til it runs like it's supposed to.
Bigger than stock cams want more initial timing. Not so much a big-small block thing really.
That sounds about right my 466 wouldn't run worth a crap unless it had atleast 18 initial regardless of total it wanted 18 initial. The cast iron heads like timing!
What affect on starting "hot" did it have,if any ?That sounds about right my 466 wouldn't run worth a crap unless it had atleast 18 initial regardless of total it wanted 18 initial. The cast iron heads like timing!
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.
