Got a smokin deal on a older but brand new nitrous kit, tried to sell it, no interest in it, so i put it on. Going with a zex 4150 plate.

this is almost exactly what i want to swap the top end over to on my combo if i decide to keep the engine.

Only problem I've had with this plate is the IAC sensor went out after about a year and the tps only read 2.5 volts. Had to turn it up side down turn it until I could get 4.6 volts out of it.

My machinest wanted to see what it would do on his dynojet, with it untuned and only 24 degrees, it made I think 409 running 15:1+ afr, converter unlocked, at 6500 and still climbing.. With it tuned and the timing back up I'd be happy with 440-450.
I do have a super vic carbed intake with a NOS fogger and msd 6010 I'd sell.
