I can't really think of anything inparticular to check for on an LS1 that you wouldn't look for on any other engine. If you're mechanically inclined you already know what to look for. As for the steering wheel, I dunno about a 5th gen wheel in a 4th gen. I can't imagine it looking anywhere near right but if you wanna try it go for it! If its just that you hate the look of the wheel with no radio controls for some reason but would be ok not having them maybe consider a MOMO wheel? Other than that, get one and have fun! I know its not a 5th gen, but its still a fun as hell car that's fast enough to make you look like this guy ===>
