Finally dynoed APE 370, Patriot II's, 238/244 I finally got my car back together and running again after toasting the motor last Thanksgiving. I have a few electrical gremlins to work out of it that are causing a random, crazy misfiring. Other than that I am happy with my numbers in its current stage of mods. The mods are as follows:
Big props to the gang at AP Engineering. I showed up a little late and had to fiddle with my car on the dyno. No complaints from them at all. Kirk, the tuner, helped me attempt to diagnose my problems. He noticed that I had an exhaust leak on the passenger side that I was unaware of. Chris, was very helpful in answering my seemingly random questions throughout the day mainly on my future mods. All in all I was there for over 3 hours, but my car made it home...on the way there, I figured it would not make it.

Yeah, good numbers. Kirk did my car also. He knows his stuff. I'll be back to see them in the spring.
Pick up some of those boltons over the winter and head on back.

The cam actually does not act all that big in a 370. It definately is not stock, but drives as good or better than my TR224 cam did in my 346 untuned. Even with the SPEC IV, it is very streetable. There is an obvious difference in acceleration at any RPM though.
Vince....I will probably go with the 90/90 Fast setup. Eventually some Kooks or QTPs also.
Whplash...Kirk definately knows his stuff. He did not hesitate one bit to begin troubleshooting my car.
My goal with this long block is somewhere around 430 rwhp on APE's dyno. Then it will be time for a cam, head, and crank swap and who knows what else, turbo possibly. My final goal with this car is 550 rwhp on a dynojet. This is what I see as the limit for a streetable car that I drive to work daily in the summer. Big cubic inches and a small turbo equals a very mild dependable setup, which is what I will want eventually.

It was going to cost me the same to buy a shortblock from APE whether it was a 348 or a 370, so the choice was easy. I had to buy a new block because I scratched one of the walls in my aluminum one, so I just bought an iron one. At the time it was purely a cost issue. I got a bigger motor for what turned out to be cheaper after I bought a new block.
I could not beat the price from APE either. Awesome deal on the shortblock and great shipping charges....I picked the motor up.
