converting VS V6 to v8

[SHIFT3D]

Hey all.
Just recently picked up a 5lt/trans/kframe pretty cheap and so i decided that Im gonna rip my v6 out and put the v8 in, now my questions are what needs to be changed? such as radiator? Fuel pump? whats different in and around the engines?

What state are you in?

Fuel pump should be ok, so dont worry bout that. Radiator, ecu and engine wiring harness(or just do memcal instead of whole ecu) exhaust headers ect.. You will need v8 springs to hold the new motor weight, though the v6 ones will hold up, just not as good, tail shaft. Theres prob more but thats gonna keep you busy for a bit.
