1958 348 block with crank No rods or pistons. Casting date H 2 57 ,suffix T 920 HA . Casting number 3732811. Should be 1958 348 3 deuce with Turboglide. Has to be 1 of the earliest 3 deuce blocks ever, cast Sept 2nd 1957. BAD news has a crack near the deck where W motors are prone to split. $300 or best offer you could be the only person in your neighborhood with 1 of these. Great wall hanger !! Thanks Bill
