Seems to be a lot of these popping up lately. Mine is a August '68 cast 270 block, 7BL suffix. I've found a few very desirable engines in the old cabin cruiser type boats in graveyards over the years. Those usually have corrosion issues. The racing boats usually ran a closed cooling system, from what I've learned from researching the sport.
