expected idle?

[33 IMP]

I didn't read anywhere that this is a drag race only car. This is what MVA can do.....

Top of post #12.
1/4 mile car, no street driving.
So.... I'd still set total timing where it needs to be, and set idle speed where it's comfy in gear, and where it ends up in park is where it ends up.
1200 in neutral wouldn't surprise me or bother me.

Virg,
The centri curve & total mech advance is the LAST thing you do.....
The First thing you do is get the idle timing correct. Failure to do this will result in the car not performing at it's best. One member has already told you his combo needed 60* at idle. Hint, hint.

I appreciate the education G. This is the first engine beyond OEM/mild street stuff for me, so I'm hesitantly taking the steps forward towards the numbers you have been showing. It's not that I don't believe you and others on this site, with WAY more time and experience under the hood, than I. It's just that I'm taking steps into an unknown for me.

To determine the correct amount of idle timing, you do this simple 5 min test:
- engine warmed up to operating temp, mixture adjusted as best as possible, engine idling in gear.
- slowly rotate dist CW [ advances the timing ].
- keep going until you get the highest rpm/smoothest idle. Toggle the dist to make sure.
- now check what the timing is.

Report back with the result & we go from there....

I will give that a shot.
