If you definitely want the ls1,I would recomend finding a donor car to strip the drivetrain from.Then get the car together and running in stock lt1 form. wait to do any serious mods until you`ve got more money to play with.(besides, a stock lt1 in a 2500 lb car is no slouch) you can always do more later, try to avoid getting so much money and time into it, that you get buned out and bail on the project early. If you have the car painted and looking nice, it will help to keep you motivated. The problem many of us make, is stipping the car and having this ugly hulk sitting around soaking up all of our extra time and money. if you take your time and do a little at a time, it will cost less and you will be more likely to finish
