Hey guys is there any more HP hiding in my 6.0? it is an 07 NNBS truck with AR headers with full exhaust, volant intake and custom tune. I think im going to get a pro truck 3200 yank converter to help some, but i was just wondering if there is anything else I can do with out going to cam and heads? People told me that TB porting wouldnt work... what about intake manifold porting or an underdrive pulley? any of that stuff? Im just looking for some more ponies and wondering where to find it. Thanks alot!

UDP will free up a little more if you want all there is to get or you can look into a set of worked heads but you'll want a cam to take advantage of them. I'd do a cam before UDP, but that's just me.

Porting the TB won't gain you anything, it actually lost 4rwhp on my tahoe until over 4000 rpm. I will post up the dyno graph someday, just need to scan it in

what about not going into the motor? would different roller rockers help? what does the 1.8 mean?

You do not want to go with 1.8 lifters if you are ever going to cam it the reason being is that most of these cams come on so fast that 1.8 lifters cannot keep up thus hurting performance and possibly your valvetrain/engine.

What If I never cam it? Would any kind of roller rockers give me more performance with the stock setup? Is there a writeup on this? how do they make more power? with the ratio or the less friction? thanks!

You could do ported heads and raise your compression to 11:1.

well, how about no cam and heads mods.. is there anything else? can I gain from porting the intake manifold? how about those rocker arms?
