i want to build a 383 for my nova. someone i work with's dad has a 4 bolt block out of an 88 truck. he's said he let me have it for $200. the problem is that he broke one of the main caps cuz he put it on backwards of sumthin. he bought a new cap said i just need to get the cap matched and line bore the block. another friend of mine's dad had that problem with his 454 and he said that i'm going to be getting into lots of money if i get this block. he said that i can't just get the one cap, that i'd have to get all of them and the machining is goin to cost lots of $$ and it might not be worth it. now i figured i'd have to get it machined anyway for the 400 crank, but i've never done this before and i don't know if the block and crank get machined or just the block or just the crank.
