Bob, If you reread my post, it say's , diamond, ross, keith black pistons and unnamed crank and rods. All names of different piston manufactures that supply pistons to those kits, not that there the same manufacturer, there might be more also. Regarding the no name crank and rods, who is the supplier of those? could be eagle, scat , cat or dog .
it's ok to butt heads, just don't do it with a butthead
