Its not for the weak of heart when swinging stock rods in a 5-3/4. You have to take quite a bit off of em to save the block to keep from cuting too much out of the block. If you know where to grind the rods, and countersink the lower rod bolt into the cap. Just have to keep eye on the threads on the sides, you can cut some off, but too much and you will snap a rod at the bolt. Cam gets thinner between the lobes,, We cut em on the lathe, and have not had one bend, but it could happen. You will have to trim the bottom of the block bores so the rod will swing. There is enough there if your grinding on the original block, and not running a pressed in sleeve. If the aftermarket sleeve seam is set too low in the bore, your trimming the sleeve too,,, Which can be done, but your risking leaking water into the oil from the sleeve getting hot from notching it. With a 175 block, you should have bore in the block left over to still run on the original block. Id hardblock it up to the water plate anyways just to be on the safe side. H blocks get thinner at the bottom, and at 5-3/4 with stock rods, the piston skirt will be comming out the bottom of the cyl, and needs to have a good cyl wall strength. The 350 block should be ok in that area. H blocks you gotta watch out. They are not as thick as the late blocks. Piston selection is good at 3-13/16 - 3-7/8 bore. ChadS
