Did you get any baseline numbers before the h/c? I am intreagued because I dynoed 280 with stock internals, boltons and a slipping tranny, although I dont have as much drive line loss.

i did loose a little down low until i programed it .....i did not dyno it before.. it wasnt a planed deal my motor blew up and i just built another one .....i dont this truck was only rated at 275 fwhp from the factory so i was happy .....i have 33 inch tires on this truck i know it has a ton of drivline loss....also the cam is very streetable ......im not sure what the compression ratio is but its aroun 9 to 1 i think ....im planning on a radix in the next month or two ....so i built it low comp.....i think the setup will really make good power when im done...

OK, I see now. I am still curious about this cam though. You said it pulls to 6K? I would think by looking at the specs that it would pull a good bit higher than that, or have you just not taken it past 6K? Did you happen to advance it any when you installed it? If not, advancing it 4* may bring back some of your lost lowend.
