318 4 bbl and intake upgrade

Actually, you were the first one to say somebody's post was wrong. You did it first on the first page. And it was me... LOL. Now, I'll say it again, I suggest a 3310 Holley. :)
And again, that is a "big" carburetor that can be made to work, because of the type it is. I can tune one to run well on a slant 6.
