- I should have been a bit more specific about the engines. Both the 2.8L
- and 4.3L engines are Chevy. To recap, I'm most interested in the following
- information:
-
- Relative engine weights (how much heavier is the 4.3L engine).
-
- What type of motor mounts would I need.
-
- What type of tranny it'll bolt to.
-
- Any major obstacles such a swap may hit.
-
- Thanks,
- Cliff
