Need help tuning a six pack

Tune in the center carb before you start with the outboards.

They're not much harder than a 4 bbl Holley.

Think of them as a Holley 4 bbl with two sets of secondaries.... (Now that's a spreadbore....)


I'm in southwest burbs of Chicago. I'm a little familiar with Holleys.... I may be able to help a little.

PM me an email address, and I can give you a few tips.
