2.8 to 350 swap

781 Views 5 Replies 4 Participants Last post by  Boudreaux55
I've got an 83 with the 2.8 v6 that I want to swap to a 350 small block. I've got the engine. A 350 4 bolt main.

I've been digging in the forums and can't find any thing so I'm asking here.

What all parts do I need for the swap other than the engine?

4 bolt mains means it's most likely out of a C/K3500 1 ton truck or van. What year is it? Casting numbers on the heads and block?
Since you have an 83 there is a good book that gives you step by step how to. It's dated material, but so is your truck and engine so it is just what you want.

No, they are different in more ways than just the bellhousing. Gotta have a 90° 700R4. One from an 89-91 V8 truck or van would be the best choice. The last few years they were made were relatively strong units. Use a 4.3L torque converter since those will have a slightly higher stall speed behind a V8.
The 83 700R4's are pretty weak would be toast behind a V8 if you could get it to work. later versions had an auxiliary valve body and other improvements.
