I've searched on carb tuning, but I only see tuning tips for 4-bbl Holley's, Edelbrocks and Q-jets! Anyone know where I can find or have any tips for a 390 CFM Rochester 2-bbl..?

The only thing I can think of is Rochester carburators by Doug Roe. There isn't a whole lot in there, but some. Are you looking for tuning for performance, or just things like idle? The stuff for quadrajets, holleys, and eddys holds true for the two barrel as well, as far as idle mixture screws etc. goes. Best of luck.

Best way to tune a 2 bbl would be to remove it from the intake, take a picture and post it on E-Bay. Replace intake and carb with a 4 bbl setup......... ;) Just joking..... I wish I could help. graemlins/waving.gif

Here's a guy that does Rochester 2-bbls for derby cars:
