Got a few questions, how strong is the stock bottom end? I know the Rod bolts are weak but the motor is a 99-00 motor. The heads I have are iron so I know theyre pretty much junk. Would a set of 241 heads be a good setup with a nice cam?
Also not sure if its gonna be EFI or carb yet but How bad is the LS1 intake? I want to shoot for 450-475rwhp with this thing.
