What do you need to know? Build it as good as you can afford basically. Its pretty simple.
Stock block filled with block fill to mid frost plug, 4 bolt billet mains, scat cryoed crank, eagle rods, diamond pistons , vortec heads (or brodix if you really want to go fast) billet 67 turbo. Oh and a 4L80E after you blow up your 700r4 3 times.
