I just picked up a SBC 350 for my car the other day. I didn't get to hear the engine running but I kinda believe the guy saying it was a good engine & it looks to be in good working order. He said it was a Jasper rebuild & it had about 22,000 miles on it from the time it was put in til it was pulled. It had some kind of "Warranty void if removed" think stuck to one of the freeze plugs on the front. It spins freely & it looks clean under the valve covers when I pulled them off to inspect it except where they were leaking. The outside is a little oily from valve cover leaks & the intake looks old. The heads look like some type of aftermarket heads. Should I remove the heads or anything else to check everything out before I clean it up & install it into my car? What are the normal things you guys look at before dropping it in? I plan on doing a couple things...New gasket set, double roller timing chain... What else???
