7044513 that Cliff is helping me with
Cliff Ruggles:
That's one reason we bought property WAY out in the country back in 2003 and built our shop out here. There isn't anyone close enough to us so that we're bothering anyone running loud engines and such.
Back when I lived in Pittsburgh Pa there wasn't a week went by someone didn't call the Moon Twp Police and have them pay me a visit for doing exactly what you were doing!.....Cliff

@Cliff Ruggles
Long time , no type!
Wanted to bring you into the new chapter on this car and possibly a little direction from you.
I just got the car home from the body shop with new skin on it. While it was in there, I decided to change out to Pro-Filer 195CC heads, Edelbrock RPM performer and a 1" spacer. Everything else remained the same. Well, everything except the converter that you helped me out with, Tri-Shield 9.5" 3500. Very tight for getting about, instant flash to 35K when needed.
We slapped the motor in before paint and ran it a little bit. I noticed that I had to increase the angle of the primary blades to keep it running. Mixture screws had little to no effect. At the time I'd figure I would deal with it later.
Well later is now. I figure with the added flow and assuming air velocity, I'll probably need more of both idle air and fuel. Before I go digging into this too deep and leaning over fresh fenders and such, I was wondering what your thoughts are on the changes needed for this increase in flow.
I'll add a gratuitous car picture once I figure out how.

What 1" spacer, 4 hole, fully divided, fully open, semi-open?.....
kilowattkid:
it's a 4 hole Mr. Gasket - https://www.summitracing.com/parts/mrg-3406?seid=srese1&gclid=CjwKCAjw8symBhAqEiwAaTA__GC_Slj7t_ZUYZGt82_mPwx9KogBnPZlWgCayYTAbZbdSvWFVGShWRoCeQ4QAvD_BwE

The reason I went with a 4 hole is that I thought it would leave the pulse signals the same. Apparently I am wrong. I should have researched this site a bit more rather than thinking I knew what was needed. It seems that I would be better off with an open spacer or no spacer at all. I would like to read your thoughts though on the science behind it.
