Hi guys i post alot, i know... its just that i feel i aint getting enough power on my car .. [2006 gmc sierra 2500hd 4door 6.0L]

i had a few modifications this week... the following parts were installed:
Comp 212/216 0.520/0.524 , Borla headers , Tci clutches , Kn filter, nology plugs, removed cats, hp tuned and i got 301rwhp/ 445 torque.

what do u guys think if i install L92 heads + L92 intake, will it fit with my cam and what is the expected rwhp gain from the L92 heads and L92 intake..

thanks guys.

 

typo??

you only revving it to 3500?

what gear on the pulls? stock tires and gearing? Can you post up the chart? Sounds about right (if you meant 301/345), i made 276 hp and 330 tq with similar mods minus cam and cats...

 

Bigger cam, thats a baby cam for a 4.8 even.

 

^^ yeah that is a really small cam for a 6.0
