I`m building a 383 stroker for a friend in Ohio and the bad dog I`m working on it with is freshoning up a blown 427 bb chubby in his shop which apparently went high 6`s in the 1/4 mile in a rail and what do I see? Stock main bolts...........no joke and it`s going back together the same way. Just thaught I`d share and there was just a BIT of cap walk. Now I feel totally confident running my 1/2" arp main studs that were in three different motors for over 15 years.
