Is this a 5.3 or 4.8

10 over your ls1 and use a 4" crank with correct pistons


4.8/5.3 is same setup. take to 3.9 bore and use 4" crank

I can pretty much fab anything so I'm not worried bout Anything, I'm just at a learning curve on the new tech stuff.lol My brain needs an upload with this LS stuff. I also have a 55 Chevy Sedan that has a 454 thats fuel injected, but I always wanted an LS1 in that baby. So I will cut my teeth on the 5.3 and maybe the Sedan will get that LS1 after all. I love the way that engine looks.

Also does any GM drive by wire pedal work or do I have to look for a certain year? Thats the only think I did not get with the engine
