    Question LS1 rebuild

    So the LS1 in my 2001 Camaro SS developed a knock coming from cylinder #1. Unloading that cylinder makes the knock go away so my mechanic thinks it to be piston/wristpin issue and I've pulled the motor.

    My question is I plan to do some performance upgrades if the damage isn't too severe while I have the engine out. Probably just cam/headers/tuning.

    However, out side of that are there any basic things you SHOULD do to an LS1 when rebuilding it? What was the fix for the cold piston slap issue? Just want to make sure I take care of anything that would be a pain later. Also, any fixes for the oil consumption issue?

    Finally - whats a good street/daily driver cam that doesn't require (but could still benefit from) custom tuning? Also it should be compatible with the stock TQ converter.

    My current mods are SLP cold air and Corsa Catback.

    Thanks!

    Honestly, just slap a 228 in there, you will be happy with it. Also, just count on the tune. Piston slap isn't a problem per se, just a reality for allowing the eutectic pistons to expand. (Spelling on that one?) You could go to forged pistons. Hopefully, everything is alright and you caught the rod knock before any major damage!
