Yeah, i never thought they made a standard, but maybe they do.
I can't even remember if mine had the F stamped on the actual piston. This is what i found on the TRW L2379F. It also answers other things i allways wondered about like valve releife volume and clearance. My spec sheet lists them having a min clearance of 1.5 thou, but at the pin. Less than i thought.

Re: forgies or hypers

I would have someone check it out for you UCNTRY, crack test as well. That was you know exactly what you have, and may be stop you doing damage to the motor and losing the money you have invested.

The F indicates forged. No letter indicates cast.

Re: forgies or hypers

I thought TRW (now Speed Pro) only made the piston 2379 or 2379F as a forged piston to suit the 351 Cleveland with 4V 63cc heads to have approx 10.5:1 compression. I think Sealed power is the name of Speed Pro's cheaper pistons which r cast or hypereutectic pistons. I think anyway !!!

Re: forgies or hypers

while were on the subject does anyone know if the ACL racer series are proper Forged pistons? Are they a good choice for performance stuff?
Some info seems to say they have 2 compression rings while other says they have 1, im confussed!

Re: forgies or hypers

I'm sure ACL Race Series r all Hypereutectic pistons. Think their good for 400-450 hp and 10-10.5:1 comp ratio. The pistons to suit the 6" 302C rod with the 351C crank came with 2 versions. (I think Part No - 9357) The 2 ring piston with 1 comp ring and the 3 ring piston with 2 comp rings. The 2 ring version which I have r good for the weekend warrior with limited street use cos of oil loss but if u change ur oil every 10,000 km it won't matter (u should anyway). Go to ACL website as they have a Tech Bulletin on the pistons.
