i bought a car that has a v6-v8 swap already done to it.
i was wondering what are some things i should check to make sure were taken care of in the swap. the car was orginally an 85 v6 and now carbd v8.

there are 2 switches on the dash that i don't know what they do.
the tach doesn't work.
the front springs are way 2 weak for a v8. i keep bottoming out.
what else should i look at?
