I have a set of Diamond forged pistons that are still in the original Diamond box with the spec. card for these pistons. The spec. card has the name YUNICK on the upper left corner so I'm sure these were for a project of Sonny's back in the day. Some of the packing newspaper is dated 1985. These came out of his estate after he passed on. Here's what's on the spec. card..
Piston Spec. Card
Bore Size = 4.003
Stroke = Then says Comp. Ht. 1.590
Ring Grooves:
Top = 1/16
Second = 1/16
Oil Ring = 3/16
Pin Dia. = .927
Pin Length = 2.750
Pin Locks:
Type = 5107
Width = .043
Amount = Double
Piston Wt. = 540
These are pistons ONLY ! NO ! wrist pins.
Someone should be able to use these in a 4.1 build??
If nothing else these would be a Rare collector item.
I'll take $400 and $25 shipping and insurance for them in the lower 48. If you'd like pics. send me your email and I'll send them.
