Pistons have about 25 passes on them excellent condition you would have to replace pins as the pins that were in there were coated and I used them on another build. These are custom JE lightweight Pistons 4.3750 bore. $475.00 these were 1100 new
What would the oversize of these pistons. I'm assuming they are forged. What would the comp ratio be with 64 cc heads and a 027 head gasket. I'm in line
I attached a copy of the spec sheet from JE that List all of the specifications . That should answer any of your questions
These Pistons would give 475 CI with 3.950 stroke and 6.800 rod and piston .010 in the hole. Compression would be between 12.5 and 13 .1 depending
Sure you can get less compression by adding a thicker head gasket are having a piston down in the hole I thought the guy wanted compression . Since the picture clearly illustrated it was a flat top piston so I was giving him the better side of how I would set it up with tight quench for power . But you wouldn't know that so you just like to add your opinion
When I first looked at these I didn't realize they were for such a oversized cu in I'm presently building a 462 and don't want to start over with new rods etc. It hit me at 2:00 in the morning what they were but I had already inquired. Sorry for the confusion. I was looking for about 11-1 or 11.5-1 and realize the thickness of the gasket and deck height can change that a lot
No problem at all yeah these are for more of a strictly race deal where you fill the block and you don't have to worry about getting thin in the cylinder wall due to having it filled.where if somebody wanted to run them with a good oil cooler that would work as well
