Ok. 97 v6 dead, aquire low mileage 01 v6. Told have to make motor look like 97 to the comp. So have to use 97: wiring harness, cam sensor, fuel system. So can't just switch fuEl rails because heads are machined different... there is way more to thexcept 01 than the 97. So do I change intake, heads, everything on top over to 97... also heard I have to change cam. Will 97 heads work on this 01?
