TA Buick performance in AZ. has the 4 rear neoprene seals for a Buick 350 in their catalog for $16.95. I have a 72 350 4bl intake manifold if you are looking for one.

That's priceless!! An old-time rebuilder advised me that a rear main seal for a 312 Ford would work in an Oldsmobile 307 and that the rope seal could be avoided altogether. Didn't believe him until I tried it.

I thought the 460 Ford worked in 455s, and the 350 took the same seal as the V6. Long ago I worked at Jim Ruggles' when we switched from rope to rubber. I thought the seal we used was from an AMC, but it's been a while.
I see that FelPro sells a neoprene seal for the V6s BS40613. Either way, make sure to polish the knurls down or it can chew the edge off of the neoprene seal (that much I do remember).

Interesting, every Ford 312 I ever rebuilt used a rope rear main seal.
They did have a pressed in rubber seal in the front timing cover however.

231 has 2.500 main journal diameter. 460 ford and 350 buick both have 3.000 main journal diameter. Fel pro bs40032 is the one to use.
