i think best bang for the buck is to take your origional heads and get them ported and polished, maybe even get them plained to obtain a higher compression ratio. Aftermarket intake is something i'm looking into, Edlebrock makes a real nice one.

first--thanks for the reply--afraid I may not any--being a newbie to the 4.3 (not motors) I have been doing a lot of reading--it looks like 94/95 heads with the 30 degree angle are some good bolt ons???
These are going into our off road buggy--with no ommissions to contend with--Also I wanted to keep the TBI--so we can run at different elevations, with out alot of tunning----
What would be the minimum computer requirments be for somthing not running any emmissions--but keeping the TBI--I understand, they sell a adjustable mass senser??--is this true--R
