Awful dyno numbers need advice
Thanks, and Trevor offered to send me another cam...I just want to exhaust all other options before I resort to that because I have to pay the installation fees again to have the new one put in.
bro i ran 14.74 on juice and the guy was like.. GET IT OFF MY DYNO NOW! lol.
Backyard mechanics will blow your motor everytime.
14's you want AWAY FROM.
12.5-13 is perfect.
I run 12.9 all across the board
14.7 lol

oh yeah lol.
Get yourself a nice mcleod twin disk or a cartek clutch.
My cartek grabs like a ****..doesnt chatter AT ALL and can handle juice/boost/stroked.
No more burnt clutch smells after a big launch!

i havnt read all the posts, but have u rechecked the preload on the rocker arms? i know if that is off it can rob horsepower (but not as much as u r losing i think) just a suggestion. good luck man
I have heard of the big dyno numbers with cam and headers no heads. But two guys local are only making 413 and 420rwhp not sure their torque with heads,cams,longtubes and one has very large cam.They have ls6 and one has lsx intake. One has all bolt ons..pulley,ported tb.The 420rwhp guy has the lsx and doens't have pulley or ported tb.
I would think you are really only missing like 15 rwhp maybe. I didnt' see underdrive pulley or ported tb in your sig.
Also what clutch are you on and what condition is it. A slipping weak clutch can easily take away some hp and torque if you can't get it to the rollers.
Also would check basic stuff..plugs and wires..fuel filter..

Vandal is correct about the rockers. But it sounds more like you have a clutch issue.
You mention the power numbers but what does the curve look like? I understand you have no way to host it but, could you give is hp/tq ratings every 250rpm so we can plot it?

12 anything will produce the power your looking for, that guy is out to lunch... big time, Trust me the real dyno is the track trust your tuners and installers give em time this stuff aint gravy.dynojet' are mighty hard to tell if they are driving thru the clutch...just a thought
I will post the dyno this weekend. And for all you guys doing the math (300 hp plus headers cam=360 hp) You're forgetting one thing, My torque is 335. There is no mathematical way to explain that. I will get a clutch soon and re test it, but I never noticed the clutch slip once before the dyno. O Well thanks for the advice..Ill keep you posted.
here is what it looks like when a clutch is slipping:

and here is what my car did when it wasnt slipping:

obviously u would be able to tell if something is going wrong (depending on how severely ur clutch is slipping) hope this helps
