I have a beautiful 1995 Camaro Z-28. It has 166,000 miles on it. My problem is that I blew a head gasket and with the high mileage, I know that I need to change the bottom end as well as the top end. If I'm going to do all of this, I figured that I will buy an LT-1 block from a junk yard here who deals in mostly Camaro's and have it transformed into a 383 crate. I would like to get as much horsepower as I can from this since the transmission I have is a high performance tranny. I'm thinking about 550 horsepower if not more without having to install a supercharger or nitrous. Is there anyone who has done a mod like this to explain to me in as much detail as possible what I would need to do in order to accomplish this. Would LT-4 heads help? What type of cam shaft should I get? What's the best type of pistons and connecting rods should I get? Is that LT-4 package that I had seen in the Summit Racing Catalog a good buy? How about timing chains?
