Which nitrous kit?

416 stroker, 10.7:1, all forged, steel crank, 500 ish hp at crank. 518 od tran, 3000 stall with anti ballooning plate, 3:91 rear. In a 74 barracuda.

I've had nos in 2 stroke atvs and sleds but never a car so this is new ground for me. But I definately know what u mean about addictive!!

Is it necessary to have a purge valve ?
