Hey Al,
I've been going to this board for a little while now and most of these guys know their sh*t. If for some reason ya don't get an answer go to Fletch's Carbed 5.0 site. Most of them are "old school" carbed guys and can answer any question you throw at them. I'd love to help, but I'm a little new to the carb thing. His site is at:
http://www.geocities.com/MotorCity/Track/3553/
He's got a msg board,tech articles,projects, links, and all the usual bs.
Hope this helps,
Lee
