I have a steel crank short block with LY rods. Quality machine work and Balanced. Its kinda like a balanced New Yorker replacement build short block.

Its not worth using up Indy or Victor heads I have in Aluminum to make compression with a 5900 shift point engine in am available a or b body.

I'm thinking about a Turbo build with small Garrett twins.

Will this piston design (5/64 ring) be ok to build to 15psi?
if so, should I call CP to replace the moly rings I used.

I see their modern Coated Stainless rings are a better choice.
Im unsure if 5/64 top and bottom are available for such an application.

Pistons are .060 down. While on the subject, would a 906 Wedge head at 88cc (8.8:1 CR) or a 516 at 78cc (9.8 CR) work better considering quench.

Trying to do this in a 72 Charger Street Car..

Thanks in advance!

One of the big problems with the trw OE replacement style pistons in higher hp applications is the poor wrist pin oiling situation.
They will often gall up the pin bores if you make decent power or turn a lot of rpm.

Hi Duane, Thanks for the reply. Intend to keep it below 6000 rpm with a 323 gear.

I assume with boost it will make enough power so this would still be a concern.

IMO, just not really the right part for the job, although I'm sure many will disagree.

As they say....."your results may vary".
