Kyle;
From 1969 to 1974 were the best blocks (IMHO),in 1975 Ford changed the casting somewhat and made them a little lighter in the bottom end............
If you plan on doing a stroker,I would have it bored/honed with deck plates and have the mains line honed also, re-surface the deck,along with a good vatting before hand,pull out all of the oil galley plugs and make sure they run a wire brush thru them in the cleaning process and re-install the pressed-in oil galley plugs with screw-in NPT plugs.........
As a side note; a couple of weeks ago I brought my 1971 302 block to the machine shop for boring/honing/etc.etc.,to build my 331 with,the machinest was putting a 1990 302 block on the boring bar to bore,we turned over both blocks to look at the bottom of the cylinders and the webbing in the bottom and it was very evident with the naked eye the bottom end of my 1971 block was "beefier" than the 1990 block........the machinest even said there was quite a bit of difference in the lower cylinder wall thickness........
