For Sale Offenhauser 3x2 intake manifold for a 364 Buick. Rare one engine only model in excellent unmolested condition. It’s a little dusty from years of display in my shop but it doesn’t look like anyone ever ran it. Please note: it does NOT fit 264-322 directly (see below) and definitely does not fit 401-425. $275 plus shipping UPDATE: I bought this manifold thinking that the basic casting might be the same as the 264-322 casting just drilled differently. I recently tried it on a 322 and it looks like that might be the case. The casting aligns with the heads and the ports are very close, the bolt holes need to be ovaled about 1/8” inward to align with the early heads and the bolt hole bosses are somewhat oval shaped so it wouldn’t look wonky.
