I think he was talking about the vette lt1 and vette ls1 None of the accesory brackets are cmpatable from either engine design. I know for a fact that you can put a 400 behind an ls1 with no problems. There is one that was at the track in a z 28 last time was there. I think someone did the LS1 swap and got their gauges to work with it. I think allen has a 94 that has working gauges with an ls1. As far as overbores are concerned what can a 6.0 be bored to? There are also 6.0 blocks on ebay for about 500. That beats most machine shops or at least the one i worked at. Has anyone heard of procell? I have heard good and bad about them. I was never done wrong by them and my motor held together. There is no way i would sell my truck now. I just got it painted. With over 250,000 miles on my truck a dealer would only offer me pennys for it. Sorry bastards. If i did sell my truck and got a loan then i would have payments and full coverage insurance for a 21 year old male I dont even make enough money to pay the insurance I only work part time because of my school. I think the new trucks are a little to plastic for me. Plus i want to have the satisfaction of updating my truck. What is the ls2? I know its probably a dumb question for yall. the only dumb question is the one not asked. Also im not exactly made out of money either if i didn have that much money i would probably pay someone to do the conversion for me and not worry about the satisfaction of doing it myself. However i do appreciate the ideas and suggestions. I learn more in one hour of reading on this site than i do in three hours of history class
