I am getting an ls6 cam kit for a good price and was wondering what the hp gains and 1/4 mile gains are with swapping it in? I have seen a coupke thread were guys gained a little over 30 rwhp with the ls6 cam but also seen where guys say they are only worth 15-20 hp? If i could gain 30hp and 3 mPh in the 1/4 mile i would be happy. Im really wanting it for the lack of top end i have. I usually get pulled up top 110 mph and up and i figre the cam will give me ALOT better top end. The duration is not a whole lot more than the ls1 cam but it looks like u pick up some pretty good lift...

1998 - 2000 Fbody
202/210 int/exh @ 0.05" duration
0.496" / 0.496" int/exh lift
116 LSA

Ls6 cam specs
204/218 int/exh @ 0.05" duration
0.551" / 0.547" int/exh lift
117 LSA

How much of a gain is hard to guess, but probably not really worth the effort and price of a tune, springs and gaskets.

i ran consistent high 12s with an 02 ls6 cam with stock manifolds,stall and gears. i did need a tune though.


imo its not a great cam if you want killer top end.

I got the kit with cam, springs, and pushrods for $235 shipped and i get retunes for $100. So adding in gaskets and fluids i should be into it less than $600.

If you're in it for that little and you do the install, it's not too bad.
But you could also stick a gm hotcam in there if you don't want to spend a lot and get more power than the ls6.
You could use the ls6 springs too.

The Cam alone will get you maybe 20 HP. If you have the cam and intake the results will be decent.

I didn't know you could use a gm hotcam with ls6 springs?

The hotcam has less lift than the ls6. You could also run the gm ASA cam with ls6 springs AFAIK.

Yes I agree the Hot cam is a little better because of the duration @ in 219 ex 228 @ .050" lift and lift of .525" . This is a decent cam for a factory cam but if You have to buy it new I would buy an after-market cam instead for maybe $100 or so more,,,,,, You will see considerably larger gains both in the low to mid-range tq but also in the top end hp . I'm not sure about the LS1 specifically but Car Craft did some testing with the LM7 5.3L from a junk-yard and with a carb, carb manifold and an MSD ignition controller and some LT headers they got baseline #'s of 350lb/ft and 335 hp then added a *****-Thumper cam and valve springs and gained 96hp to 431hp and I believe 15lb/ft to 365 and that also raised the peak rpm from 5600 to 6800 in a junk-yard 5.3L

^^^Yes, I completely agree. I would go aftermarket myself, but I got the impression that the OP is on a budget, which is why I mentioned the gm cams.

this would work better than the LS6 cam
use with PSI maxlife beehives

The LS6 cam is a great budget friendly cam,
however after you endure all the work
necessary to change it out you will wish
you spent a few more dollars to gain
35-40 horsepower instead of 15-20

I have a ls6 cam

You should pick up about 25hp with that cam.

Yes you have it right^. I like the idea of the ls6 cam because it will be very simple to install, I can still get great gas mileage, it's really cheap compared to a new cam kit, and it will be easy to get a mail order tune with it and not need a dyno tune. I'm on a 100 shot also so I don't wanna big cam that will cause me to need a new fuel pump/injectors... Probably getting close with the 100 shot actually. I just want about 3-4 more car lengths up top if that makes sense. My car pulls great down low to about 105 it falls on its face a bit and that's usually where the m6 cars pull on me. If I could have the extra 30 hp from the ls6 cam I would have the top end to stay up in front.

I'm sure I will se ATLEAST 20-25 rwhp with the ls6 cam. I have full bolt-ons to accommodate it so I think I will get pretty good gains. Plus I will bump up my shift points from 6200 to about 6450 and I should see some good gains.

I'll reply to your PM tonight, I have been slacking I have about 6 to reply to. LOL

The Ls6 cam is perfect for what you are wanting and fits the budget as well.

You won't notice much gains at all down low, the gains you will see will be above 4500-5000RPMs. I would recommend shifting around 6300ish RPMs, from what I have seen that cam likes being spun decently higher than an ls1 cam.

I could see 30HP with a tune... 20HP would be on the low side. Not bad for the money invested IMO.

I would consider some Katech rod bolts at the same time..........

I'm not looking for big gains down low. A couple car lengths in the 1/4 mile would make me happy. I just know I will gain a pretty good amount of top end with a cam like this. In my old lt1 z28 I would reace a friends 96 lt1 vette and before he would pull me about 2 cars in the 1/4 mile and than rape me up top horribly. Well I put in a little hot cam and we were about even through the 1/4 and than it went from him pulling me 3 cars to me pullin him 3 cars or so. I figure the 100+mph gains will make it worth it for me.

Anybody want to guess what I will gain with the ls6 cam? My mods are ls6 intake/ported tb, LT headers/ory, Slp lid, ftra, 3400 stall and pcmforless tune. I will be getting it retuned when the cam goes in... I seen people get decent gains without the mods to help the cam so I figure I should see slightly higher gains with having the engine bolt-ons and the stall for the cam

If you could find a pair of cheap 243 heads...

I would do a set of milled 317 before 243 if on a budget. You could buy a set of 317 and have them milled for cheaper than a stock set of 243. they would flow identical but give more low and mid range from the milling.
