Back to the LS7, I bought some Mamo 265 heads (Trick Flow castings) and a Mamo MSD intake. Seems like with this top end kit I can get away with more cam and still drive decent. I'm scoping out other Mamo builds to get an idea what they've got for cam. TSP 3.2 and BTR Stage 4 are also pretty high on my list.

I didn't see anything on their site called a B3. I did see a Stage 3 cam for supercharged LSA and LS9 engines. Is this what you are referring to?

Anybody have a cam card for Brian Tooley LS7 Stage 3 and Stage 4? I need the intake valve closing event at 0.006 or 0.004 lift.
I called them today but they accidentally gave me closing event at 0.05 lift. Too late to call them back for the weekend.

The cam card I got with my 4.2 did not have the IVC specs.
I just finished the install and tune on the 4.2 cam. Car put down 626whp and 566wtq on SAE correction. Roughly 30-35whp gain over the BTR stage 3 and -10ish wtq. Definitely drives different but I wouldn't say it's terrible.

Do you have a torque curve you can share?

They are very secretive about the cam. IVC on it is 52, IIRC. My tuner has his cam card. I'll see if I can get it from him.

Personally, I’m not a believer in the B3. I ran a B3 equipped car last night and got him by over 2 cars. He made more power than me on the same dyno/tuner.
