Have Tony spec you a cam if you already have his heads and MSD.

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.

I tried that already and didn't find an LS7 cam card. Mostly LS1 and LS3.

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.

And I would like to see the RPM B-3 cam card too if anybody has it. Can't believe I'm even still considering this cam after being denied that info from RPM.

That's a lot of HP difference. Wow!
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.

Thank you, jayyyw.

Imagine if the Comp Cams catalog didn't have any specs..... just seems laughable, huh?

Its not the same comparison. RPM designed the cam. They are not the only company to keep specs a secret.

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.

Biggest reason I went with TSP. Plus, the lobes they use. My valvetrain is quieter.
