Reply to "Hypereutetic v Forged"

panteradougMember

I've used cast, hyper-cast, and forged.

The forged pistons are really overkill and unless you are going to drag race this car and hit it with 200hp worth of nitrous, they are definitely over kill.

The Keith Black hypertutonic is a good piston and all that you need.

I have them in my 347. In that engine, the interesting thing about them is they weigh 347g vs the 521g of the stock forged piston.

The engine balancer just didn't believe that and kept weighing them, saying "this just can't be".

In the early 70's one of the trick pieces to put into a Pro Stock small block was super light pistons like this.

They all had to be "carved" out of the forged pistons by hand to get them that light. Now you just open the box and install them.

The piston pins are 102g for these pistons too.

The engine revs like it is an electric motor with an aluminum flywheel.

I vote KB pistons.
