no it's locked thats why I asked. I can tell it's alot stronger now than it was with full bolt on's so i'm guessing it was a stingy dyno. the man said he has a car with a fast intake, ms4 , ported 243's and my car put the same power down and more power thru the power curve.

Id also check your fuel pressure, noticed you said you had stock fuel pump & injectors. Atleast put a racetronix and some 42s in it to fuel it

The numbers seem kinda low, but the graph looks very good, right on par with dyno graph. I have the same I/E set-up as you but am running 243 heads. You also have 4.11 gears and its hot as ***** out, so that is eating up some HP right there.
I bet you will do well at the track, this cam is nice as it gives you early useable torque and carries well up top too, here is my graph just to compare.

That is way low, You should be in the 440+ range.
Look at your fueling.
Did you do a base dyno?
What is your exhaust setup?

This is what to expect from this cam in a properly done setup;

Cam only C5 then add heads/90 (Cartek 4x)

with trickflow heads and a 230* cam you went 11.6? i don't think that is a good number at all for a head/cam stalled auto car. what did you trap? 116?

i agree with taking it to the track, but decent cam only cars will run 11.7s @ 115 all day.

Put some injectors on that bitch and then I'll guess 400whp.

I've been doubting this set-up as it seems everyone never gets what they want out of the el torro cam unless everything is perfect. No matter what the master of valve events on here says this cam isn't for everyone.
