Yes, nitrous is one way to do the trick. In that case I'd use premium engine components so it will handle the extra power output. A high quality forged crank, high quality rods, high quality pistons, top shelf rings and bearings, excellent machine work, head studs, cometic gaskets, etc. Then you should be able to build a very mellow 600 hp street cruiser that easily runs 10's with a 100 or 150 hp shot. If you build the engine and the driveline to handle 750 hp then you should be good to go for a long time. That means a beefed up transmission, heavy duty driveshaft and a Dana 60 rearend.
