Anyone running On3 w/ AC?
A cam for boost would definitely help as well as meth to help with the long Gevity of the motor. Go with a colder stage of spark plugs and if you want to do the one by one method you could put head studs in or just be smart pull the heads replace the lifters do a cam swap put LS9 head gaskets on it and head studs and your ready to go. I still would not run much past 10-12lbs of boot on a stock LS1 if that is your motor. The stock bottom ends aren't very strong and don't last forever at high power levels.
