'71 block??
I've failed to get up useful info searching. I've heard there is a difference in the '71 block. Is that so and if so what would those differences be and does it matter in a truck application.
thanks sooo much!

The only difference I can see in the block is the screw in core plug above the lifter galley on each side. There is no evidence of the block being stronger. I used to have one around here but I junked it.
