Thanks, the number is 5d8002727 an on the other side there is 24b04a but the b is a weird looking character, not quite a b. I am thinking about buying this from a guy I know, just wondering what it is.thanks
V8 I think Blake is right. 57 Super motor. It should be 8 3/4" center to center on front intake bolts if it is. Judd
The 364's are cool, great motors. They share the bellhousing pattern with the 401/425 which means that you can get a TH400 for it, or if you can find a bellhousing put a four speed behind it real easy. The hard parts for that motor are intakes and flywheels. They are different from all the other Nailheads . They are out there but not as readily available.

[/ QUOTE ]Correct me if I'm wrong Scott, but can't you use 401 heads on a 364, and then use the 401 intakes? I'm pretty sure my 364 is a 1963, and has 401 heads on it. That is what Fatass told me anyway.
After looking at http://www.buicks.net/shop/engine_ident.html I don't think that is the way it works. The early 401's used the same head casting as the 364 which puts the difference in the block and not the heads. So I would say you'd end up still using the 364 manifolds. I'll ask on the Nailhead list again just for clarification. Though I know you can use 401/425 heads on the 364. You can slot the holes on 401/425 manifolds to use on a 364 but the ports don't line up correctly and would take a little work to fix.

The distance in the manifold width is the best way to tell. The early 364 and 401 used the same heads. The difference was the deck height. The 364 is all to itself incuding the crank. We will have bellhousings ready next month to install a chev manual trans behind the 364/401 and 425. Welcome to the nailhead world!
