I was wondering if quench zones are as important for efficient running on a turbo motor as they are on an N/A motor.

I would assume not since the air being forced into the cylinder would cause quite a bit of turbulence, but i figured I should ask just to be sure.

Right now my intentions are to build either a turbo 352 or 390, but both motors that i'm starting with are 10.5:1 motors. I'm looking to drop one down to about 8:1 and it looks like using a 351W dished piston with rebushed connecting rods would be a pretty easy way to get there BUT with the shorter compression height of the 351W piston, I'd be running alot of deck.

Any input?
