8 3/4 chunk math - sticker shock

Since you already have the 741 you might consider just building it up how you want it. Not sure what the price difference would be since the parts for it might be a little harder to come by, but you woulnd't need to find a rare case. The 741 should probably handle it fine, it's pretty underrated if you ask around. If you just wanted to drop a new sure grip unit and gears in it I would think you would cut your price pretty significantly over basically making one from scratch.
