Ok lemme start from square one just to make sure I am properly following what you are saying so just to clarify...
You have a 6.2 out of a denali going in the V. Is the motor complete? If so, in your first post, you said you will be getting L92 heads. Now I am probably mistaken but doesn't the vortec 6200 already have L92 heads? Also if you are going to not use the pistons, you might as well sell the kit and get something you really want. If you buy new pistons and then sell the ones you aren't using, it isn't going to net you as much money as selling the whole kit as one set. And I'm not sure why you don't want to use a 4.125 inch bore, as far as I have seen and heard, it is safe to do. The issue most here are having, is the machining necessary on the bottom end of the block to properly clearance it for a significantly larger stroke. Also have you confirmed that the 6.2 is usable? What kind if damage has been done to it, if any? That makes a huge difference on whether to do a whole build on it or not. If it runs, sell the rotating assembly and then machine the heads and toss in a nice cam with the money and leave the bottom for now. That would be ideal. Heck you could come out with extra cash that way. If the 6.2 doesn't run, then that's a horse of a while different color.
Did the 6.2 Denali also get an aluminum block or is this iron?
