Still on the fence about a LS2 vs a double roller of a yet undetermined brand. I was reading about people with M6s worrying about the chains cause of the harsh RPM changes in an M6. Just wondering if a trans brake would also beat up on teh chain at all? I knwo its not as harsh just wondering how harsh it would be? This will be on a built blown motor making some pretty good #s.

 

Also does anyone have the GM part # for the LS2 timing SET, not just the chain?
