I'm swapping a '76 350 into my Iroc i'm going to be running vortec heads and probably a demon carb so I'm thinking that it will be making some good power. I need help in deciding which type of piston to get should I get forged or will they be overkill? Or should I get hyperteautetic? pistons. Does anyone know what are the advantages and disadvantages of the two types? Any help would be appreciated.

 

The reason for running forged pistons is if your running a blower, or nos. If your planning to run higher than 6000 rpm, you'll need a forged crank, and rods. If your going to run a tpi unit under 6000 rpm with
it naturally aspirated and no power adders,
the hyperuetechtic (spelling?) pistons should be fine.
