V6 305 Head Compatibility (Between Models)

[TRybas]

Gentlemen (and Ladies),

Can anyone confirm the compatibility between heads and blocks throughout the years (models) on the V6 305’s. I have a 1960 305A with a cracked head and leads on heads from different models (305D, 305E, ect). I thought I saw it on here years ago that they are interchangeable but I’m coming up blank on my search.

Side note: If anyone on the east coast ever comes across a 305A please reach out.

Thanks in advance,
Tim R.

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 !

I recently sold a 1960 B-Model truck with a complete 305 A in it. The buyer was intending to put the B-Model cab on a rat rod and was not planning to use the 305A. It is in southwest Missouri and if you want I can get his contact information.
