CAM DETAILS:
BTR LS3 STAGE 3 CAMSHAFT
Specs: 229/244 .615"/.595" 113+4
The LS3 camshaft lineup was born from an assortment of custom grinds, dyno testing, daily driving, and real world experience. This camshaft will not require any flycutting of pistons with OEM LS3 combustion chamber size. If you mill your heads, it is always advised to check piston to valve clearance is at an optimum level. We have seen 480whp from this grind and supporting modifications. It will require a 3 bolt cam gear and proper valvetrain components. If you're application has an automatic transmission, consult with your tuner for torque converter needs. We advise an aftermarket stall for this grind.

Year ago, installed in LS3 a BTR Stage 2 cam, valvetrain upgrade: trunnions, springs, seals, pushrods; tune. Dyno'ed at 451 rwhp on dynojet with factory NPP exhaust. Everything else is stock. Have about 8k miles since done, still doing fine. Looking back, would like to have done a before-cam-swap dyno pull so would have a baseline comparison. Figuring a 12% drivetrain loss (so I'm told) on the stock 436hp nets to about 380rwhp. Comparing that to what I gained, I figure 451hp minus 380hp nets 71 hp gain. BTR says will gain 67 hp, so sounds about right. The peak hp is found about 200 rpm higher than stock peak hp. Good driveability with manual trans. Might have less desirable street manners with an automatic trans.

Are you saying you liked it or was expensive power for what you got?

So 500whp -530 is it possible with this cam and support mods ect

Yes I added a BTR stage 3 with new valve springs, retainers, clips and hollowed-our my stock cats. Picked up 58 WHP! My motor is making 520+

440 whp with JUST A CAM!!

[@dennisrobinson8008]

These are great numbers. Do these get up to 600rwhp with better cams?

[@DoctorDNF007]

Will this be ok for PTV clearence on a 6.0 with 823 heads? Stock gasket thickness.

[@Kanawiggz_]

Could this cam be used with my current 2800 stall? What type of gain can I see on a 6.2 Sierra?

Fuel?

Nice

[@HunterM430]

Lookin to get this cam for my ls1, hows the drivability?

[@WEHRWULF8814]

It's great, drives like stock with my 6 speed. 431rwhp with cam, longtubes, and tune only. NEVER stalls, ever.

Who cares 😂

[@HunterM430]

@@jesuslopez973 those are low numbers bro, you should go to a new tuner, a cammed ls3 can crank out 500whp all day

Is that's a 2nd gear pull?

[@m.m.6757]

1st gear.

[@PiterStreak]

IMW FTW

[@timmyahhh]

How did you get the rev limiter to stop like that? Or was that the dyno not letting it go higher?

[@C6Z_Bob]

What intake did you have? Stock?
