The LS1 is actually banned fom Engine Masters.

Does coating the pistons or bearings help at all with detonation resistance? I know a super tight quench and a good tune can help this. Also, the double quench pad of the new aftermarket castings seem to be designed to help reduce detonation.
If it's still detonating, put some Torco in it (I think with the price of gas, one could almost fill up on Torco now for a similar price).

I'm not trying to rain on everyone's parade as compression is very important but I hate seeing people build stuff that might give them problems later on.
