Found this question and response in the Archives previous posts section;



I'm not sure now, but are all the V6 engine "blocks" from 305A,D,C,D,E, 351C,E,M, 401C,M the same physical size. So oil pans and all head combinations will bolt-on without any problems?

Yes, All 305A,B,C,D,E, 351C,E,M, 379, 401, 401M, 432, 478, 478M V6 engines, other than bore sizes all share the same basic block architecture and dimensions therefore cylinder heads, corresponding intake and exhaust manifolds, valve covers, pushrod covers, distributors, water pump-timing cover housings along with corresponding water manifolds, camshafts, gear drives on 401 to 478, chain drives from 305 to 379, crankshafts other than 73 to 74 478M, oil pans, oil filter housings are INTERCHANGEABLE !
