Default 355 Rebuild Dyno numbers

So I finally dynoed the LT1 like a week ago at Danny's shop(Lethal Performance in SA). I put down 380 RWHP and 353 RWTQ... I have the video of the pull on my comp if anybody wants to host it. I was really happy with the numbers being that I just have a little bitty ole hotcam in the car. Next step is a BIGGER CAM :-D Anyways somebody let me know if they wanna host the vid. Also it only has like 2000 miles on it... Will it get stronger in the next couple thousand miles?? If so, how much?

Not bad. what heads are you running? I have a 355 with hotcam and stock heads. I put down 346 rwhp and 355 rwtq. I know there is more in my motor, but Im getting around 62,000 counts of knock at WOT. It has been there since I built the motor over a year ago. Still got a 12.759 @ 111.00 spinning 1-3.

That's crazy, never seen a hotcam make peak power at 6100rpms before, those heads must flow like crazy.

in Austin? They sponsor LS1tech and do bad *** head, the numbers are good for that little hot cam. But with a bigger custom cam that puppy could make close to 400.
