89 360 engine

I understand. It's that it would be a bummer if he did all that and the engine would be shot. I've noticed that some people can't wait to bolt on a 4 barrel and headers without having any knowledge of the condition of the engine. I've only put a used engine in a vehicle one time and that was because I knew the guy that rebuilt it, other wise I always tear down and go through them first.
It's tough responding on internet threads. We don't know how knowledgeable a certain member may be and who has time to type out each and every detail. It should go without saying that you should check a used engine out before bolting it in and expecting it to run. Although I have. You buy a used one from a salvage yard you expect it to run unless it is sold as a core.
