How far did you pull it too and what was your a/f number? I thought it would make more power but still nice to play around with.

Don't worry about the dyno numbers. to many factors: load, weight, and other things that tuners don't get to specific with. Not to mention you have an auto. Just have fun with it man.

thats sounds right, upgraded heads probably add 100hp and leave torque same or a touch higher.

Id leave it, it'll lve alot longer and still be a low 11 car.

Remember, about 14.6 PSI almost doubles your N/A power (all things being equal). So if your N/A power with your setup is about 280, 12 PSI should be about 350.

As othes have said, I would not get hung up on dyno numbers if you are a drag racer. Only the time matters :)

Sounds good for pretty much a stock longblock. That's exactly what I want. Put a bad ass suspension in it and go enjoy it.

No disrespect intended but your numbers seem low. I would expect closer to 400 rwhp and 500 tq on your set up. I suppose it could be attributed to many different things including the type of dyno and if you were running drag radials.

I have had two cars with the on3 kit and have been on the dyno with 4 diff combinations. The lowest was a stock 137k shortblock, procrap heads, typhoon intake, stock cam and 4.6psi through mufflers. It made 345rwhp and 385tq with the engine hot. It should have made more but we had a prob blowing out spark at 5k. Turns out is was a bad alternator/week battery.

I am planning on putting another kit on a stock 5.0 w aod soon and will post the numbers for comparison.
