Default What do y'all think

Cam and Headers installed and tuned for only 2500
What do y'all think about that package on a denali sierra? Would my truck still be fine for everyday use? Would it kill my mileage? And about how much power do y'all think it would add? Thankyou

Wow this isn't a bad deal considering
Comp Cam or Texas Speed cam of your choice (custom cams available upon request at no additional charge) $380
PAC Racing .650 lift valve springs $150
Manley 7.400 Chromemoly Pushrods $99
Pacesetter or TSP longtube headers $390
Pacesetter or TSP off-road connection pipes $150
NGK TR6 Spark Plugs $25
MSD 8.5mm Spark Plug Wires $80
Fel Pro gasket set $50
GM Crank balancer bolt $8
Mobil 1 oil, filter, and coolant $50
Professional Installation
Custom Dyno Tune $300
That's about $1600 with out labor.
You would most likely see about 120hp gains in the average 6.0L

It has the 6.2 do you think it would be about the same? Do you think it would hurt my truck over time or lower my mpgs?

Nah, not happening. That's a super optimistic number which I doubt is going to happen for those mods. I think 100HP---TOPS.

I would just make sure this guy is trust worthy.

I also don't think its far fetched to get 100 HP from headers, cam and tune coming off a bone stock truck. Of course it depends which cam you go with and how aggressive it is though.

What year is your denali? Is it a flex fuel truck? Do you run flex fuel? Typical upgrades that are done along with cam and headers would be a looser stall converter to help make up for the loss of low end power, and fuel upgrades. Maybe think about replacing your muffler and putting a different air intake on there while you're at it.

I'd say something in the high 2-teens intake duration and high 220's to 230 exhaust duration would be fairly mild mannered.

220/230 or so. I have a 222/226 with the older style heads and its not bad at all. Your heads have a much more intake biased flow characteristic which requires a tad more on the exhaust side.
