Thinking of buying a high mileage LT1
What are some things I should look out for when buying a hi mileage car? I know that optispark can be a pain sometimes, but summit has cheap replacement units. It seems to me that head gaskets blow on LT1 cars with hi miles pretty often. What other stuff should I look out for?
If I get it, I might put new head gaskets in it just for cheap insurance. After that, I'll prolly just install headers and have fun until it blows up or I sell it.
The opti isn't that hard. i've done it twice in 2 months because i went cheap the first time. Got a new GM unit and been good. I've read or the headgaskets but they aren't all that hard to change i've heard.
. The Opti harness should have been replaced when i put the first new opti in but i got dumb. Let the old stocker in. Then when the new opti case cracked i replaced with the GM one and then the starting problem. Changed out the harness for the opti and boom, started right up. The connector was all dirty and bent up. Runs great now
Really though, if it runs strong and drives fine, you shouldn't run into too many problems. I don't notice any more head gaskets going in LT1s than any other engine. That normally happens from overheating. Don't let it overheat, and you'll be fine. Higher mileage LT1s have a tendency to spin a bearing when hit with a cam/head combo. I'm not sure what you want to do to it, but if doing anything crazy, just rebuild it.

Good luck
Several of the people who have posted above are 100% correct, if the car was maintained well, you will only have to tinker with it and deal with the normal issues.
Get the car - mod the hell out of it and enjoy it until it is time to get the new one.
