Nope. the 455 has a different bolt pattern. You will need an adapter.

Pontiac blocks do not use Chevy tranmissions. BOP (Buick Olds Pontiac) ones are named that for good reason.

My friend has a pontiac 350 in his 72 Ventura and runs a turbo 350. I thought the 350 and 455 were based on the same block?

No.

There are Chevy and BOP versions of both of those transmissions. Identical guts, different bolt pattern on the case.

I just called my friend and it all makes sense now. he has a universal bellhousing turbo 350, so that is why he is using a turbo 350 that bolts up to either or.
