Hi all,

I have a 1966 GMC 3/4 ton pickup with 305 V6 big block. The Stromberg carb has had it and I’d like to replace but having tough time finding a 2bbl carb that will fit to current intake manifold.

I like the Holley 2bbl #7448 350 CFM. The current four bolt pattern on manifold is 3 1/4 X 1 7/8. I tried to find an adapter to accept the Holley carb but had no luck. Any advice?

Should I have an adapter machined to fit current manifold or replace the manifold in order to mate with Holley carb? Thx
