Hey! Just wondering if anyone knows if you can use a 4.3 block from an early 90's blazer and swap all of the '96 4.3 vortec heads/intake/etc. onto it?

I've got a '96 that threw a rear main bearing, and I'm looking for options to repair it.

Thanks!

 

Probably not. There is quite a bit that could be different. Without more specifics on the donor block, it really is almost impossible to say for sure.
