Need Cam Help for Aircooled 3.8

[c4srojo]

I am building a 3.8 for an '84 911. I hand grenaded the 3.6 that was in the car...but, I was going to use the intake and cams from that car for this build.. The cams are Shrick 0005-880-02.
This is for a dedicated track car.
A friend has some OEM Cams that, he believes came off of a Cup Car. The part number is 24707.
I have searched to the best of my ability and have not been able to find out anything about these. I am looking for a flat torque curve but trying to get a little more top end out of the car.
If you are familiar with these cams and their benefits/negatives, any guidance would be appreciated.

Thanks.

Tim,

Your choice of intake systems really dictates what cams you can successfully use.

For any OEM intake, stick with RS cams. Cup cam LC's are too wide for any single-throttle intake system.

Hi,

We are going to use Webcams 20/21 - for our current ongoing 3.8 build
1992 964 stock intake - JE 102MM 12.5CR pistons - EBS racing valve springs, etc.
The 20/21 are high lift and short duration for better torque numbers

What happened to your 3.6 engine??

Regards,

I was passing a guy going into #5 at Putnam Park. He decided to drag race me to the corner, I had to stay in it. I have to feather it going into that corner as I am at the top of third, but I was committed, the limiter didn't catch it and KABOOM.
I think it was a rod failure. Handgrenaded it. It was running spectacularly well too...which is what they say always happens.

247 07 is a stock left side '95 street cam

Cup cams would end in 2407 70
