This is a used set of Wiseco forged flat top pistons for a small block with the following specs:
This is just the pistons with full floating pins and spiro-locks. No rods. These are for use with a 4" stroker crank. These came out of my 340-based 416. They will fit a .030-over 340 or a .070-over 360. I went .010 more on this refresh, so I can't use these anymore.

With a 72cc chamber you should be right around 11:1 compression.
Mine with 56cc was 13:1.

Bore: 4.070
Comp Ht: 1.460
Rod: 6.123
Volume: -6cc
Pin: .984
Rings: 1/16, 1/16, 3/16

Asking $500 + Shipping

Easily under 1000 miles. It sat for a few years and only recently I decided to freshen the combo. It saw maybe 25 passes at the track as well. I had rocker arm oiling issues for the longest time with a set of prototype rockers that didn't oil worth a crap, and I got tired of fighting it. That's why it sat for so long. It was eating up the cup end of the pushrods every time I ran it. I'd make 6 or 7 passes, and I had to change pushrods...and with these being Smith Brothers custom pieces, it was getting expensive. I got the problem fixed with new rockers, and decided to add a trans-brake and some other stuff. Pulled the engine to freshen and go as big as I could this time with higher compression.
