I picked up a 1990 5.0l h.o. long block for $150. It's for my 1984 gt 350 4cyl turbo project. I am very excited to do a little rebuild on it, been sitting in a garage for a few years. Ill post pics when I get some time.
I got my head off and measured the bore. I can see some wear on the major thrust surface of the block. I am .005" over. Set my bore gage to "0" at 4.00".
Pistons are still in the block, i could not measure the bottom of the cylinder. This area had the most wear and seemed like the best spot to get an idea of overall wear. The cross hatch is still there and very prominent. It's a little more wear then I like, but it will due for a fun weekend cruiser.
Just got the block and crank back from machine shop. They did a clean and polish of crank, clean of block, light home on cylinders and install cam bearings.
