Trailblazer engine swwp
I have a 06 trailblazer with a blown 4.2 i6
engine. I also have 91 s10 with a perfectly
fine 4.3l. my question is would the 4.3 be
compatible and how complicated would the
swap be if it is.
Anything is possible, but I think you'll have a problem mating with the Trailblazer software. That swap would be more complicated than a v8 swap, because TB's had an option of a V8.
