what is the timing for a 454 year is 1975 to 1980

Depends what you got, 31 degrees is probably a good place to start!

I think you need to find out if he want's initial or total first. Where'd you get 31* from?

 

[airboat]

well initial isn't very improtant if 12 degrees gets you into 43 degrees and detonation at WOT

Initial advance is pretty much the end result of how much total timing you have minus mech. advance. You can taylor the amount of mech. advance and you can taylor how quick it comes in but total timing is what will determine if your engine lives or dies. It is really the MOST IMPORTANT TIMING SETTING you can make. The rest is tuning. Each Bore size, rod length, piston marterial and fuel, I'm sure I'm forgetting a few but those are the majors that will affect the total timing you can run. I don't run vacuum advance on my stuff because it's not on the street so I'm not going to get into that right now.

Still don't get it.

For lack of info on the first post, I would guess he's looking for initial timing.

I did a edit to furhter try to explain.
should be places to find factory specs on the internet? I'f it's 6 degrees it will probably have better responce with 12 degrees but if your going up that long hill towing at lots of throttle and your total timing is correct it shouldnt be a problem. If total is 38 degrees in the same situatiion you could have problems. I like everything in by 3000 rPM for sure!

OK, I agree with that. But now I'm picturing this guy trying to set his initial at 31*. get what I mean? Like someone painted over the tune spec's under his hood. Getting cold up there yet?

 

[airboat]

Yeah I was just trying to make a point! It's Fricking snowing and about 26 your temps! :drunk:

We have had so much rain this year everything is still green. 3 3/4 in. since yesterday! I'm down in So. Indiana about mid 40's at night but their starting to shiver in the N states. (big cold front out of guess where). I think it's going to be a cold winter this year! Good 4x4 weather!!!
