When going from a v-6, 3.1mpfi to a v-8, what parts of the electrical system need to be changed to be able to work with the v-8?
Also, is it cheaper to convert from the 3.1 to a v-8 or is it easier just to go out and buy a new 3.1?

Thanks,
Bruce

 

get a 3.4, if you want to stay with a 6. cheaper too.

look for KED85s 2.8-3.4 swap boogie.
