4.3 is here. No pics cause the lighting in my garage sucks. It turned out to be a 1990 motor with 23X,XXX miles. I'll begin tearing it down soon and replacing anything that looks worn.
Question for the Chevy guys. Is the ecm different for the auto and manual trans on these TBI motors? The one that I have is currently hooked to an auto.
