Just out of curiosity...

Are there 350 crate engine mount kits for the blazer and would doing such a thing cost a lot of money?

 

depends on if you are going carb or FI. Check out jtr.com for mounts, exhaust, etc.

 

buy the swap manual from JTR. Worth the $20 bones.

Define cost alot of money?
It can be a very easy swap. depends on what you have now and what your trying to stuff under the hood.

 

costs depends on what your all doing and what you already have a 4x4 costs more money to do the swap in.
