std on piston crown

Rambler60 wrote: I am currently rebuilding a 60 flathead with 55k miles. The owner parked it due to mechanical problems in 1978 and gave it to me 2 years ago. I pulled the engine and tranny a couple months ago and tore it all down. The head nuts were loose and #6 cylinder was full of solidified antifreeze. Other cylinders were fine. I just looked at the original pistons and they are unmarked. I bought a Sealed Power replacement piston off eBay that is stamped "std" for #6 but the ring grooves would not accept the Ramco rings I bought from The AMC Store (Dale Cooper). So the original standard pistons are not marked, standard replacements are. I am having trouble finding another piston for this thing. Does anyone know where I can get a 3 ring forged piston with rings? Good used parts would be ok as I probably will only drive it to the occasional car show. Pretty slick, all original old car.

Thanks for the advice. I bought a Sealed Power piston in the original box on eBay. The box was marked in pencil "AMC 196 FH" but it would not accept the rings that fit the original 3 ring pistons. Ring grooves were too narrow. Called Dale Cooper at "The AMC Store" and told him my predicament. When I received the piston he sent, it was a 4 ring and much heavier. Called him again and he said that was all he had for that motor. Now I am a little leery. I have rebuilt everything from flathead Fords to Mazda Rotaries and this Rambler motor has thrown me several curves. At age 70 I am still learning new stuff. I will try Kantner's. Farna also recommended Egge. Thanks to everyone for your interest and input. What a great forum!
