Who wants a mopar turbo kit?!?!

Yes, a turbo is MUCH easier on parts to make power with. Not only does the piston maintain more pressure on the exhaust stroke (which is easier on rods/rod bolts), but more importantly you end up running a lot less timing on a turbo motor. As max pressure gets near TDC, it just tries to push the crank straight out the bottom of the block, rather then rotating the crank. Turbo (or any boosted motor), runs less timing, so the peak pressure is later. That means the crank angle larger, so you have forces that create more rotation (and less force against the main caps).

My personal motor is a cast crank/stock block 360. It does have good rods and pistons in it, but obviously the crank especially isn't anything special. The car has been a best of 9.55@144mph at 3740lbs on 23psi of boost.

So we'll see how much a truely stock bottom end will take, but I'm guessing the pistons are the limiting factor more then anything.
