Very easy to do and one of the best ways to have a streetable motor and still make the 500 horse goal when needed. Build a good strong bottom end with forged pistons. Then build the top end to the 350-400horse level with one of the many SBC combos. Dont let the static compression get too high. 9 to 9.5:1 would be good for a nitrous motor. The right combo wont require a high stall converter. Get a good 250 horse nitrous system and set it up per there instuctions. As a rule I like for anything above the 150 horse lever to have a separate fuel supply to the gas solenoid. The main thing is to monitor the fuel pressure at the nitrous fuel supply and the carburator closely. The W.O.T. top RPM fuel pressure should not get below 5-7 psi on both the carb and the nitrous.

If the system is set up right a nitrous motor will last for many years. Many of my freinds and I have done have done it thoughout the years and had zero problems with the motor. The problems you have will be with the rest of the drive train. Transmissions have to be built for sure. Nitrous makes alot of torque and torque breaks parts if you are getting traction.
