forged vs. hypereutectic

which one should i use for pistons? im getting a 383 shortblock and am planning to get 500 lb.ft. of torque and around 450 horsepower out of it, and the guy at M&R engines said that although it is gonna be a daily-driven street vehicle, i should have forged pistons and not hypereuctetic. this will also be subject to some cold starts in the winter, since i live in nebraska... most other people said to use hypereutectic for its tighter clearances and less wear over time. basically, how long does a typical forged piston smallblock chevy last for mileage? i want to be able to get at least 100 thousand miles from this beast as long as i dont romp on it all the time. what do you guys think?

In general a forged piston is stronger by design but requires somewhat more clearance and is tougher on the cyl walls, tighter clearances are better for ring and cylinder wear, the choice depends on compression, rpm range and driving habits. 100k expectation I'd stay with the Hyper's

FWIW I have 262k on a set of Silvolite/Kieth Black hypers and they're just right.

Jveik - Hypers are stronger than cast, but a bit more brittle than forged. At your power levels, I'd stick with the hypers.

yeah i ordered my shortblock with hypers, cause i dont want forged due to the looser fit in the bores when cold. plus, i could have used stock cast aluminum for the power im gonna have, only 500 lb.ft of torque and 450 horsepower, so the hypers should take that pretty well
