is there anything that can be done to a 1971 360 block that would make it alittle stronger? the block has a short fill and uses arp main studs with stock caps. are there any girdles out there that work? what about aluminum main caps to absorb some stress? will be a 13.5:1 7000rpm street/strip deal. maybe 15 passes/yr for a couple years, than I will be moving on to big block.
