The engine is a 99 5.7 Vortec. It came out of a Z71 that my brother in law stuck a new engine in. I do know the history, it was mostly highway miles and pulling a light trailer some. My plan is to check it out, do any repairs, put a new intake, carb, and distributor, and put it in my 85 s10. I have a v8 700r4 to replace the 700r4 behind my 2.8. Thank you for the advice, now to call a few machine shops and look at some new tools.
