Hmm... cast pistons, interesting. Apparently GM is starting to think like me in a few area's of engine design.
That's one hell of a crate motor. I'd take it over the BBC in anything that weighs less than 4000lbs.
Just to clearify why I think cast pistons are fine for high horsepower... because they work! Also, being as they're cast they don't expand nearly as much as fordged which keeps the tolerances tighter (less piston slap and ring blowby). The other reason cast pistons are nicer is their weight. Designed properly you want the lightest piston since it is moving at a VERY fast rate up and down in the cylinder. Make more horsepower means not wasting it on stopping and changing direction of the piston and c-rod. Apparently the Ti-rods are awesome. I got to touch one as the SAE world congress last year and it was amazing. Also couldn't believe the process they used to make the rods... freeze and crack so that each rod has it's own specific cap, absolutely amazing!
Also, so long as you don't detonate or pre-ignite the cast pistons will last forever.
God I love engines and what GM is doing with the pushrod motors these days.
