Hi im new to ls1 tech, but i have several questions on modding my trans am. I have just picked up a ls1 block, part number 12550592. I have a 2000 ws6 and i was wondering if all my parts from the 2000 ls1 will all transfer over. I have a set of 243 heads being fully pp at a local machine shop. There also grindin a cam for the setup. I have 100,000 miles on the stock bottem end so i was gonna, put a fresh one back in all at once, 383? Will i have to resleeve the block?. Will this new block 12550592 work with everything if i went all stock again? I would really appreciate some help. thanx guys! still tryin to figure out how to use this lol thanx
