I have a set of Diamond -14cc street/strip pistons that I pulled out of my SDPC LS2 402 after 5k miles. These pistons are in very good shape other than having some carbon buildup on the tops. No grooves on the skirts that you can feel. The following is engraved on the bottoms of the pistons.
SD-802, 22477, DRP71 B
Here's some pics.




I'm only changing them to change compression for a FI build. All original rings and pins will be shipped with them. They are for a 4.000" bore

$350 shipped.

I also have a set of Manley -22cc pistons I bought from RICEETER on the boards here. They came out of a stock bore ls2 used in a Procharged setup.
They were sold through Scoggin Dickey. They are in the same condition as the Diamonds above and have the following on the bottom of them.
SD5D, 1107, 57014.

I was going to use these but opted to go with pistons designed for 1000+hp.

I also have a full set of Total Seal piston rings (CSH2010-5) for a 4.000" bore with 1.5/1.5/3.0mm groves. I talked with their techs and asked about 4.005. They say there's enough material there to use on a 4.005 if you're doing a ring gap in the low .020's.
Never opened them, and can't use them on the Weisco's I just bought because they use a 1.2mm grove. They sell for $289 through many popular sites.



I'll ship them for $240

 

what is comp. ratio on the diamond pistons with a 64cc head?

 

Both are for use in a 402ci ?

 

Just running it thru a bare bones compression calculator says it's around 10.3 to 1 with a .051" head gasket.
Both were used in a 402. That's where the wear marks on the pistons come from, being pulled part way out the bottom of the bore/sleeve. They could be used in anything with a 4.000 bore.

 

would these work with a 3.90 stroke?

 

Only if you can find the appropriate connecting rod, for example 6.225" with a 3.90" stroke crank.

 

payment sent on the diamonds

 

Confirmed, the Diamond Pistons are sold

 

still have the manley pistons?

 

Yes, I still have the Manleys and the Total Seal rings yet
