[QUOTE="6.4f350, post: 1249219, member: 20253"] E Best case it will be. That means this guy will go buy it, find out the block is trash, and then spend the next 6 months dealing with forum buyers just to get his money back. The only way I'd be comfortable with buying it is if you have a buddy that's a machinist that can go with you, or if you're pretty handy with a bore gauge and can get ahold of allowed tolerances. I had an opportunity to buy a whole 6.4 truck last year for $3,000 but passed. It was a cab and chassis, and the engine was out and tore down but every last bit was there. A piston came apart and the wrist pin ate the cylinder wall. I have a buddy that's a machinist that would have put a sleeve in for cheap, but I figured up that after my time putting it together, money spent, and time trying to sell it just wasn't worth it. Sometimes cheap junk is just that - junk. [/QUOTE]
