Hi, i have a 91 formula with a sbc in it that is bored .030 over. i'm wonder what i should gap my spark plugs to? i have 74cc heads and a 4 brl edelbrock carb if that helps.

get the book on the car that should tell you

get the book on the car that should tell you

Not neccassrily in this case being a modeified engine, book is based on stock specs.

There is one person here I think maybe can answer that question, otherwise I would consult a machine/speed shop or maybe the tech counter at Jeg's or Summit :dunno:

One thing tho, you bought the car this way right? If so, check the gap off of one of the old plugs :thinkerg:
