Hi guys, I just bought a 1997 chevy pickup 4x4 that had a blown up 305 in it. I pulled that out and installed a 350 with all the vortec components along with a better camshaft and shorty headers.
Now I want to tune it in and I keep hearing the best way to go is to just upgrade my ecm with a 0411 2002 van ecm. Does it matter which 0411 ecm I get? can it be out of another silverado of 2002 or something else with a V8? And I am not sure who to ask anymore about the wiring on the 97 to newer wiring. Thanks for helping me out.
