Ok well here is the deal.After many many hrs and sweat blood and tears (as we all know ) on my engine buildup.While stiitng at a light one day i heard this faint knocking noise that got louder and louder ...then i **** myself as i heard it it did not sound good ...anyways ill make it shorter upon further reveiw it turns out theat the screw that holds in the butterfly on my t/b cam eout and got sucked into my intake and ended up taking out one of my pistons and screwin up a head (i had that milled down a lil ) anyways it got stuck in the piston and broke off but my issue is that it took a lil peice out of the block where the top of the piston stroke is im ataching a pic.I am wondering if i could use the block still? any way of fixing it ? would it be reliable still ? i dont know im looking for a direction to take ..i really dont want to have to buy another block ...any sujestions are much appreciated.
