Great site to ask this question on, ask in the LT1 forum and you may get a different answer. I dont think very many people are going to give you a postive opinion on them, most dont even own LT1s. LT1s are old, they have some typical old GM problems, that one day the LS1s will have too. Nothing major, might have to change an ignition switch at some point and other general wear and tear basic parts like any older car. Optis arent that bad as people make them out to be, you dont have to change them every oil change or any thing. 95+ has vented, aim for a 95+LT1, the Optis are cheaper, and you better choices in timing chains if you choose to put in a cam. Oil leaks, the intake seak likes to leak, some bad *** at GM put the egr back there so it cooks the awesome rtv seal over time, thus oil leaks. Other wise nothing really major, they like nitrous, bit of a pain to work on, esp compared to a 5.0 but people still seem to be able to mod them just fine. They respond well to mods, its an older motor but for what they are they respond well. Its not hard to put an LT1 in to the deep 12s with full bolt ons, esp at HRP. I like em, they sound cool, not really much to know about them though, typical old car problems here and there that you will get with an car that age. Other wise, good cars to get, not as bad as people like to make them out to be. I still really like driving mine. I see a lot of the older SS and WS6 cars on e-bay for not much. If I went back in time, I still would have got one. Like I said, the people that make LT1s out to eb the worst most unreliable cars on the planet prolly never owned one. The opti sucks, but like I said, not as bad as a lot of people make them out to be. LT1 motors also last a long time, plenty with 200K miles out there, esp cop cars and taxis.
