I had a guy with a big class A 440 powered motorhome approach me about buying a use stock bore 440 car piston, the dome thickness was around .150 thinner on the HP passenger car motor and on a non HP 350 HP passenger car motor than his OEM motor home piston was with a hole in the middle of it puke shruggy work
