6.0=450hp

[chevyboss22]

i want to swap out my 4.8 for a 6.0 but before i put it in i want to do any and all upgrades to atleast get me to 450hp range what do you guys suggest i was thinkin a cam dont really want to go with a supercharger or turbo. It will be my daily so i cant get to wild

I'm doing the same with my 6.0, I'm going with a 224 cam and 853 heads, I should have a write-up with pics done by the end of thanksgiving holidays. But, if you can afford to, 243 heads would be the best gm heads for that engine. The truck engine is pretty much the best flowing intake other than the fast 90 with costs too much, IMO. The ls6 intake is a good choice if you plan on reviong to 7k often.

6.0 or nothing, IMO.

A) 450 at the crank, or at the wheels?

 

B) What are your end-goals. 450 horsepower is easily attained with a LQ4/LQ9, but a track truck has different needs than a truck that needs to pull a boat/ATV/Horse trailer from time to time.

 

Headers and cam...Then a stall if you really want to shoot out of the hole

Yup... higher "horsepower" comes at the expense of low-end torque when adjusting cam profiles. I'll take low-end torque any day, but I tow (and don't race).

799 or 243 heads. Stock truck intake. Ported stock throttle body. Long tube headers and dual 2.5 or 3" exhaust with aerochamber mufflers. 220ish range cam I like LSL or EPS lobes Id stay away from XER's for dd use. Probably need new injectors and a good single pump like racetronix or the like. A GOOD tune not some mail order crap. 2800 stall or so. That'll make her rock and roll damn fiercly and still be very street friendly. 114+2 on the cam btw maybe +4 to help your bottom end torque. PAC 1518 valve springs and some new hardened/chromo pushrods. Upgrade to Katech rod bolts and a new oil pump while your at it. This set up will scream safely to 7K RPM and still have all kinds of grunt down low.

i would like at least 400hp to the wheels it would be more for racing than anything i dont tow or haul anything would it be easier just dropping a vette motor into the truck or just to build a 6.0lq4 i do know i will need a cam and a stall at the least and of course a tune

400 whp with a 6.0 is very doable na. You have two approaches depending on budget. Aftermarket heads, or stock heads. If you run aftermarket heads like a stage 2 LS6 or some L92's then you can run a more civilized cam as mentioned above around a 224 would be perfect. If you wish to simply re-use stock heads on a budget build where peak performance is your only goal then jump up to a 240 or so LSL or XER cam and it wont be all that civilized but she'll make that number.

2001 silverado364 im still interseted to see what your outcome is let me know how it goes vvt thanks for the advice ill probably swap out the heads just so i can have a civilized dd truck until provoked hahahaahaha

Alright, still in the process of grinding valves and seats right now. As I decided to go with stage 2 862 heads instead of 853(99-00 ls1).

[VVT]

If you decide to go for heads you can really dial in your combo exactly how you want it. I would simply set a hp goal and go for a custom grind cam. PatrickG over at LS1tech does this for 30 bucks ( the cost of the cam is the same ) and then your combo will give you exactly what you want plus hes always savvy to the latest lobe designs and whos making the best grinds etc. I bought an EPS custom grind spec'd through him for my 6.2L VVT build that should hit 450 whp cam only so to shoot for 400 whp with a head/cam 6.0L will be a breeze. Happy building
