Forged can take more abuse.

I've heard arguments for and against both, having spoken to a very good, big HP drag engine builder creating massive Chev engines. He uses both "forged" and "hypereutectic" for different requirements and recons hypers can handle 1.5 - 2 HP per cubic inch easilly.
There is more to just the process of manufacturing and materials used.
Weight, pin height, skirt design, friction coating, heat treatment, engine set up, rpm, ignition timing, rod ratio, piston speed and many more factors come into choosing the right piston. For a streeter both will work.

Udo, would you class a 94x76 as a performance engine?? I suppose it depends on what I put on it really

Really? I wouldn't classify it as stock.

I think udo means " High " performance, big rpm big compression motors ( or force fed ), ive run AA hypers for 5 years now and beat the sh*t out of them, i run the car hard, 8k+ rpm always shows up on the tach recall  Cheesy for a 200 hp street car theres no need to go forged ( imo )

I prefer cast or hypers for their low thermal expansion and weight, but my engines usually don't rev past 7 and I tend to keep any boost under 1 Bar usually, so I haven't found the need for forged on my street stuff for any of my toys, ACVW or otherwise.

Thanks Ben and Modrod, this info is what I was looking for. On bens recommendation think I'll go the Hypers for now it's not a really big performance engine is turboed etc certainly not stock tho Zac
