Drill/tap the block and change to 9/16" ARP head studs, O-ring the heads (~.040) and cut receiver grooves into the heads, torque the studs to 140 lbs+ and a LS1/6 motor will hold as much NOS as you want to put in it; ~500 hp or more. I did it, as did ARE. This block and head machine work should cost you around $1500. You could then turn your attention to finding a crank, rods and pistons to handle that power.
