do you know if a small block chev intake manifold will fit on a 308 block?

308? Are you thinkin of a 307 chevy small block? if yes then yeah it should work. I dont see why it wouldnt because the 307 is pretty much the same setup as a 283,302,305,327, 350 400sb. The only dieerences r the flowing quality n valve sizes along with the casting being light or heavy.
