LS2 + C5 = grind block for motor mount clearance? On the passenger side, one of the bosses on the LS2 block (doesn't exist on LS1 block) is hitting the motor mount. I mean the metal 45deg bracket, not the cylindrical pad that it sits on. Do I need to grind the block, or can I switch to a newer model motor mount instead? My car is a 99 C5. On the corvette forum, a guy with a 2000 C5 needed to grind, another guy with an '02 C5 says he didn't. So if I had an 02+ C5 motor mount, would it clear? Or can I use a C6 motor mount, or an aftermarket motor mount?
It didn't occur to me to check for clearance there, so now the engine is in the car and bolted to the torque tube, and the motor mount won't fit.
Would have been a lot easier to do it with the engine on the hoist, plus much easier to keep everything clean.

I did a search, and MTI encountered the same issue, and has pics on the web.
