After all these years I am going to sell my Vintage Manley Pistons for a small Block Ford. I purchased these brand new from a speed shop in Seattle back in 1979. I was going to rebuild the engine and one thing led to another I never did. I since sold all the other parts and recently found these in the move we did. They are brand new old stock and are 11 1/2 to one and 30 over. I believe they are forged. The box has some water stains on it but never went through and other than perhaps a dusting and light clean.
