If you use the "search" you will find a ton of threads on the On3 kit and many include dyno results.

If you surface the heads and re install with studs, felpro 9333pt1 gaskets and get a good tune you should be able to put down 425-450 rwhp at 14-16 psi. The TQ will be over 500.

This would represent the upper end of whats possible and you'd be one bad tank of gas away from changing head gaskets and eventually splitting your block.


You can install the ic wo removing your front bumper cover but it will be a hell of a lot easier if you remove your radiator, test fit the ic, then remove the bumper cover to do the trimming etc. I started a thread on how to do this wo butchering your bumper cover and there are a ton of pics on it.

I had the same question before I bought my kit and I could not find a truly stock motor combo. Most had already upgraded with some performance parts.

I have a nearly stock motor. I have only added studs, 9333s. Everything else is stock on the motor, well except the fuel injectors if that counts. I still have all my accessories and the stock manual fan.

No real dyno numbers yet but I killed my AOD in less than 10 miles. I went and added a TH400 and now the car still severely breaks the tires loose at 40 mph and I have 275 nittos already. Street tires not drag radials. I am running 14psi and boost is so addictive. This is on a motor with either 140k or 240k as my odometer ready was exempt when I got the car.

You won't regret it, even with the stock motor.

Good to see someone from ON3 posting!
I do alot for on3, helped design the sn stuff, and do alot of testing and promoting now for them. normally, if someone has a tech question, they call me if chad or mike cant answer it. plus i do all the local installs and now offer turn key packages (depending on whats already done to the car)..
