Ok I'm selling my Ross pistons from the 6-bolt 4G64 build-up. They have a good ceramic top coating. The teflon side coating and the piston skirts have been scraped up and need to be scotch-brited smooth. I would recommend new rings as well. These pistons cost me nearly $550, 300 milse ago.
These pistons were supposed to have around 8.5:1 compression on the 4G64. These pistons have a wrist pin location set for the deck height of the 4G64 with the valve reliefs for the DOHC head. This configuration will not work in a 4G63 with out a custom rod or crank. They are not worth much to me at this point...I'll take the best offer from anyone interested.
BTW - I'm also looking for a clean and straight oil pan for a 6-bolt block.
