I'm swapping out a 2.8 and going with a 4.3. I'm going to carbarate, use headers and a vacume advance distribator. I need to know about oil pan, oil punp motor mounts ect. ect.
The 4.3 is comming from a 2wheel drive All help will be welcomed
you will need new oil pan for a 4x4 with pickup tube. it looks like some custom engine mounts will have to be made.
2.8 trans will not bolt on to the 4.3, the 4.3 and the 305, 350s all use the same trans.
