    i have a 1967 skylark with a 340 that has a 2 barrel carb. ive been thinkin about goin up for a while now, but cannot find a four barrel manifold, does anybody know a company that makes one or whether or not i could just use the 4 barrel intake off a same size buick engine (i believe they had a four barrel 340 in 67) also would i need to condsider anything else when doing this swap? thanks

    Any 340 4 bbl manifold will work, and maybe some others. You may have to adjust your throttle cable some.

    While your at it, Offenhauser makes a fantastic polished alum ribbed valve cover for the 340. They look just like the older nailhead versions, only with a high polish to them. VERY COOL !!!
