B1 vs. LS6 (Z06) cam ?
B1 vs. LS6 (Z06) cam ? I am considering one of these two cams. I have a chance for a very good deal on both. Here are the specs on the two cams:
B1:
221 / 221 .558 / .558 114 LSA
LS6 (Z06):
207 / 218 .553 / .553 117 LSA (from memory)
I know the B1 will be a little louder and have a little more lope to it. I know both will work with the 02+ LS6 springs. I was originally going to go with the LS6, but I am just wondering what kind of #`s you guys are seeing at the track with the B1. I know I`ve seen people post -.4 tenths and plus 3-4mph in the quarter, and +30 rwhp on the dyno for 01-02 cars with the LS6 cam, which is decent considering the price and the fact that gas mileage and driveablity will be the same. How about the B1? What kind of gains are you guys seeing with this? How much has your gas mileage been affected? Is the lope noticeable? I want to be as stealth as possible. I have the LT4 HOT cam in my `hawk, and I consider that a "screamer". I will be installing long tubes with a catted y. Will the cam be unnoticeable as far as sound? I am going to leave the stock heads untouched, and will eventually get a tune. Will it drive without a tune?
I have already ruled out the LPE cam because of it`s higher lift and steeper ramp rates (valvetrain dependability is a concern).
Thanks.

And you have a 2000!!! What other mods do you have?

Would you say that the cam is responsible for about 40rwhp? How is the sound? Would people suspect a cam with a catted y and a decent cat-back thats not overbearing?
Thanks.
I have a B-1 in my car with most all the bolt-ons and it surpassed all my expectations.I've considered a bigger cam but I'm afraid to lose the absolutely flat torque peak and how hard the car pulls.I give the clutch a quick slip,net high 1.7's and get into the 11's with it,thats off the street.I may try an F11 and see what happens,if I lose low end torque the B-1 goes back in.

Dude those numbers are sick

I`m not sure guys. With all the mods you guys have, I wouldnt think there would be much difference between the B1 and the Z06, plus I would be *completely* stealth and not have any real effect on gas mileage. What do you guys think?
Is it worth an extra 5rwhp or so to give that up? Decisions......

B1 all the way over the LS6 cam. This is coming from someone who has ran the LS6 cam before. It was simply weak under 4500rpms. From 4500-6500rpms it pulled damn hard for what it was, but the B1 will outpower the LS6 cam from idle to 6500rpms.
I would not run LS6 springs w the B1 if it was my motor. Taking too much chance. I've heard of LS6 springs breaking with guys Autocrossing their stock Z06's. Get a set of C918's and you'll be sitting happy.

But the ZO6 would no doubt have a better steath effect.

Wouldn`t the 918`s mean more spring pressure, which means more wear on the other valvetrain components and higher risk of the already "at risk" pushrods? I mean, the Z06 cam is very close to the B1, and I don`t plan on autocrossing where you spend extended amounts of time in the upper RPM range.
The B-1 has taken me into the 11's with a mild converter. (See sig) Looking back at the timeslips it looks like I gained about 4 tenths and 4.5 mph with it. When I first put it in my car would not idle without tuning. It does have a lope to it but you can just raise the idle a bit to get rid of it. Gas mileage took a hit...how much I don't know because I don't care. lol I switched to 918 springs when I did the cam. I bought the B-1 because many of the other aggressive cams at the time were causing loud valvetrain noise, which with my quiet exhaust would have bothered me. The B-1 has no valvetrain noise whatsoever.
