Purchased these to go on my 440, but it turns out my engine needed to go 60 over. They were listed on eBay as NOS 30 over by Midwest Classic Auto Parts and never ran and I paid $467 plus tax for them, but I can't find any casting numbers for them. Based off the design, they appear to be Enginetech or Kanter Auto pistons, but could very well be NOS. Very clean cast pistons. Just the heads and wrist pins, no connecting rods to go with them.

Asking $280 to recuperate the funds.

Compression height measures around 1.965"
