Simple question on 400
OK I have seen articles about the 400 and I read about 2v heads and 4v heads. I always thought that one was with the two barrel carb but now I don't know. Could someone enlighten me please. I have a 400 in my 55 f-100 with the two barrel. Thanks

Or so everyone thinks. I saw a 4V 400 in the 70's sitting in a junkyard in east Texas. To the OP, the "V" stands for Venturi, not valve. That's where the confusion comes from today

The 351C heads are either 2v or 4v. 400 never came with 4 barrel carb in US to my knowledge. 351C 4v manifold will not work on a 400 with 2v heads. Actually neither will the 351 2v manifold without adapters. baddad "may" have been looking at a Cleveland. They look very similar to a 351m/400.

When I see Big foot in person and get to poke him and maybe have a conversation I'll become a believer.

Correct, the spacer plates can be ported to adapt a variety of 2V & 4V configurations.
