I have a 2001 Chevy Blazer with stock 4.3L (262) SFI V6 (Vortec) engine. Had transmission and engine problems which both had to be rebuilt. My son owns it now and we just want to put rebuilds in it to get it back up and running for his first car. We have the tranny almost complete with a rebuild. Needing to find a engine that will be a direct swap, hopefully, that we could rebuild. This is supposed to be a fun, father and son project for us to do. the old engine is cracked between water jacket and cylinder head and cant use. Need to find an engine that we can use as a core to rebuild and move our aux items over to it. I know the original engine was used in many different years, makes and models. Does anyone have any information or advice on what years, makes and models would work for a direct swap? Thanks for any help/advice!!!!!
