331 Hemi Blown Help

I have a 331 Hemi and am new to building a Hemi. I plan on doing a rebuild on the core... but do i need Forged Rods and Pistons for a 6-71 Blower with a standard stroke & steel crank? I will most likely run lest than 10lbs of boost. Pump Gar and street 10:1 compression ratio it will be bored .030 over.

any info is appreciated. This will be in a 69 Dart and a street only cruiser car.


I think the compression would need to be at 8:1 or less to run blower.
