Good engine deal or not?

I need your guy's opinion on if this sounds like a good engine deal or not. It is a 1992 350 TBI unkown mileage, but he thinks it is just over 90000, with uncut wiring harness and computer for $750. Also there is a 1988 that is suppose to have 89,000 miles (same price)but it looked like there was oil around the valve covers and the covers were rusty. The 1992 didn't show any oil anywhere and the covers were just dusty dirty. I know that the filters were not OE so they have been changed. The 92 has the compressor, altenator, and power steering pump while the 88 has all of those plus something else under the compressor that I couldn't identify. I know it will not be like a rebuilt or new engine but for TBI does this sound good. Any opinions would be greatly appreciated. If it sounds good I need to move on it today or tommorrow. Thanks.

Re: Good engine deal or not?

When I'm shopping for a used engine, I usually like to hear it run. Knowing that both engines are fuel injected, and computer controlled makes hearing the engine run not much of an option. Here are a couple things I'd check on both engines. Pull each spark plug and look at the color. Let's hope all eight are about the same shade, if one or more than one spark plug is not the same color as the others, BEWARE! Look for signs of new gaskets, this could mean nothing more than just fixing a coolant or oil leak, or someone could have tried to fix a rod knock with some new bearings? I seem to remember seeing at least one new / rebuilt water pump on an engine that had been overheated real bad! If you have an engine compression tester, run a compression test on every cylinder. An engine that has sitting around will not have good compression figures, but a good engine that has been sitting around will still have equal compression figures plus / minus 10%. Make sure to have the throttle blades open when doing a compression test to allow air to be drawn into the cylinders. If it's not possible to get a compression test, then I just walk away. There are lots of bad engine deals, only a few good engine deals, just my experience.

Re: Good engine deal or not?

I concure Dave.

for that kind of $$$, Id want to hear and see it running, and STILL do a leakdown/compression test...

these engines routinely go 150K miles without major problems, but for 750 it has to be a good one, not a core with the computer stuff...
