New Engine Decision

[68302]

I have 10 grand to spend on a motor. I am debating on either getting a 408 stroker with two stage nitrous or something smaller like a 331 with a supercharger and a ton of boost. I have had a bad experience with nitrous in my last motor and am scared to use it again. the motor will go in a 68 mustang with a tremec tko 5 speed and 355 gears. it will be a custom built motor with forged everything. nitrous was fun as hell but it sent my motor to hell. my last motor was the original 302 with a cam,intake and 4 barrel. now im stuck with driving a damn 4runner until i get my motor. this is a street car but illegally race on the weekends. any thoughts, suggestions, opinions or comments would be great.
