right on barry,
the last two i bought came out of florida, nice blocks, one needed to go .030 the one i used in my car cleaned up at .008 over.
aside from grenading the motor it should outlast me.....i actually prefer the marine block as far as factory blocks, because the way they are used, place throttle at a point and it stays there, they're a bugger to get out of the boat so they are usually still standard bore when they are for sale. with the advent of aftermarket cranks with SBC journals the need for a side oiler is for bragging only in a replica, no advantage unless using factory crank journal sizes.
