I have a set of custom Diamond pistons for sale, they were run for a very short time after a friend bought the wrong compression height, he assembled with 6.49 rods and then realized the error. These were over 1000 dollars with wrist pins when he bought them with the custom upcharges.
I am selling them without wrist pins for 375 plus shipping from Omaha and insurance. Wrist pins are a common size and length and can be had from Diamond or Ross for under150 bucks.
They are beauties, and I planned to build a 396 out of them, but I just don't have time the USAF has me running so hard, even side work is being pushed out
Here is what they are, 1.73 CH 4.08 bore, 3.2 cc valve reliefs. Starting with a 352 or 360, these pistons let you use the 352/360 rod and 390 crank for zero deck at 10.160 deck height.
- with a 72 cc head and a .041 gasket, at 10.160 - 10.3:1 SCR
- at .005 below deck same gasket - 10.22:1 SCR
- zero deck and a Felpro 8554 - 10.13:1 SCR
A real handy combo for a 352/360 guy who wants a 396. They have metric rings which will bring a bit more power, coated skirts (although some slight wear on the coating, see pics)
Check out the pics and specs below. Just to be 100% clear, you will have to buy pins and rings, bore to 4.08 and use your 352/360 connecting rods and a 390/427 (3.78 stroke) crank. I highly recommend a balance job too as this is a very light rotating assembly
Please post questions here or email me. I will update if sold or pending
