sbc ,idle rpm what you guys running?

Also when you guys are setting your timing, are you unhooking the vacuum advance? and is it hooked to the timed port? I had a guy once that I built a engine for and it ran great on my break-in/test stand. Then he picked it up and put it in his car and said it had no power. I went to his house and pin pointed the problem right when I arrived, vacuum advance was hooked to the full-time port and he was setting it with the vacuum hooked up. So when he stepped on the throttle all the vacuum goes away as does the timing. After that simple fix the car ran and performed great. Sometimes you just have to check those little things.

Yeap. We always have unhooked the advance. I also found out the other day its only a 500 CFM carb.

I run it on full vacuum. Edelbrock manual for my carb said for stock use timed, for performance use full. I think my base timing is 14-17º (been a while since I set it) and it runs like a champ.

I just use the computer advance since I think it is better than vacuum advance. For those still using the CCC system, you just disconnect the 4 wire plug for the computer advance to set base timing. Then reconnect the 4 wire plug and clear any trouble.

It's even better when you can program it
