So I have never completely rebuilt an engine. I have tore one down to a short block and installed new cam bearings and camshaft but never removed pistons or crank. I bought a 1993 Buick road master with a 350 Chevy in it hooked to a 700r4 had 120,000 miles on it. The motor is a roller motor and has all the accessories intact so it should make for a decent install. The car seemed to run and drive fine but I am going to carburate it and put it in my car. I am on a very tight budget but I don't want this thing breaking down later either. With that being said I planed to to re gasket it and put a new timing chain, valve stem seals, etc in it and run it. However I am not wanting to do this a ton of times so I am curious what the best thing to do is to be sure this motor is good to go. I was thinking of running a compression check in it and while I have the heads off checking the cylinder walls etc. I did drive this car myself and it seemed strong, did burn outs, and even a donut in it before I pulled it apart LOL. I thought about a rebuild kit and putting new bearing and rings in it but I am not positive I can do it without screwing it up. I can not afford a crate engine or to send it off for a rebuild. No I'm not lazy and cheap, just plain can't afford it. Also going for a cruiser motor so most performance wise that I may do is a little bigger camshaft. (I know I'm going to be accused of half assing it and being cheap and lazy so just establishing that early.) What do you guys do when you get a used engine to check it out? What would be acceptable compression?
