Brenspeed Detroit Rocker Cams
I had these cams installed yesterday at their shop with Pypes long tube headers. I also have a C&L Racer CAI and factory 3.55 gears. The car is loud because of the FR500S axle back. The car put down 320 at the wheels with 311 in torque. The cams sound great with not much loss of low end torque.
Here is a link to my dyno run:

Not my cup of tea, but hey if your happy 
Seems like a bit of a low gain for cams though, even compared to the hot rod comparable line no?

Depends on what your car starts with. These 3v motors have dynoed as low as 240 and as high as 280. I do not have a base line to start with. My guess is that stock the car had about 260rwhp. With my upgrades 320rwhp is pretty good.

Idle sounds high - it should idle around 750 - 800 RPMS. With my hot rods it sounds choppy with the lower idle almost like it is popping popcorn. Nice cams - but I would have Brenspeed lower the idle.

Ummm, I'll save my complete thought. The cams might be cool, but I'm not a fan of rasp at all and those are raspy as hell. Good numbers. Sounded like it was higher than 6500 rpms.

Everyone that I know that has put longtubes on their car took off the KR mufflers. You might try some Magnaflows Cams sounded good after they got to idle.

dang it, now I'm getting wishy-washy about buying these cams. they sound great from brenspeeds vid's, but i'll be running Slp Loudmouths with Pypes Long tubes. h-pipe and cats. Sure wish someone would get this same setup so I could hear it before I buy it. On a side note my car was dyno'd at 287hp and 314hp stock with only my Slp Loudmouths on.

You have a good point. I was thinking the same thing. I might just get everything and see how it sounds with my Loudmouths. If I don't like it I can always buy the Mac's from Brenspeed. They're only about $330 and it's something i can easily change out myself.

I had loudmouths with NSR cams and it was just as loud as my present setup. The two Brenspeed cars have different mufflers. Chandler's car has the Mac's and the other car had the Flowmaster American Thunder. They cost $359 on Brenspeed's website. Chandler actually recommend the Flows to replace my FR500S mufflers.
