I would look into a converter though, it would help your car out a lot...Check out something that stalls between 500-900 rpm below your torque peak....

Autos dont need 400rwhp to run good times. An auto with lots of stall+gear with 320hp to the wheels will surprise the hell out of a 400rwhp 6speed in the 1/4.
Also, the area under the curve is very important. Dyno curves that look like the side view of an arrowhead are no good for the track, and no fun on the street.

It'll make more power in colder weather, get a Converter asap, who cares what it dynoes, it'll never put up the M6 numbers people love to go by, so long as it runs what it should who cares. With a good converter and tire, your car would hit bottom 12s.

Are there other cars that have dynoed at the same shop that you can compare yours to?BTW, When you put a converter in it your numbers will probably go down, but your performance will improve.

I've been talkin to Stealth and im definetly goin with the 503.... just got a question. Everybody's been saying that this cam works wonders on stock heads, does that mean that it wont gain much from some head porting? I guess im asking how much you can gain from some work on the stockers? Thanks for the input.

It really depends on what your heads will flow, if you get a good dynotune afterwards, and supporting mods. I don't think you will break 400rwhp with this cam but I'd say 380 is possible.

i have a cc503 and GTP heads and the heads really did wonders for it. i have not dynotuned it yet but i think it makes in the 370-380 range when i compare it to some other cars i have driven and/or riden in.
and no you numbers sound about right, take it to the track. if it does not perform well there then think about another tune.
