The 340 Forged Piston Is So Heavy....

Nothing wrong with TRW 73 340 (346) Duster street car running 11.03 You know how heavy those doors are.
This is the second car this motor bin in, it was in a 72 Duster. Still running strong

I also ran TRW in my 440 68 Barracuda street car that ran 11.23 back in 1989.

We now have a lot more piston to choose from.
