I can't see too much restomodding of a build sheet LS6. However, I'm usually in the "what you can't see is fair game" side of upgrading. If it were me, I would find a 1970 Hi Perf block (no '75 truck blocks, etc) and a 1970 M22 case (Any 1970 dates, not too concerned about date coded to car, esp if its an early build and date correct parts are tougher). I would fill that block with the longest stroker crank practical and a modern roller cam grind and fill that M22 with an aftermarket wide ratio gearset. I would use a light-ish flywheel for quick revving and fill the 12 bolt with 3.31 gears if it has 4.10s. It should pull like a monster and be OK on the freeway, all while looking stock and having a "correct" 4 speed with everything lining up exactly the way it should. When its time to sell, there aren't many excuses to give. My $.02, good luck.
