No. It doesn't matter what power adder, or stroker kit, the most you can get out of the stock block before it splits is roughly 450 - 500 rwhp. The rods and crank will do nothing to extend the life of the block itself. It doesn't matter how you make the power, whether you are going with stock long block and pushing 20 psi, or a hci with 10 psi. The casting is pretty thin in areas due to the cheaper casting process done back then. Ford didn't have in mind making big power with these blocks and wanted to keep costs down.
You can upgrade the rods and crank and make big power with a power adder, but you could split the block after the first run at they dyno, a few days afterwards, or later on. Sooner or later, it will split down the middle of the lifter valley and it would be time to get a R302 or dart 302 block.
