Camshaft options for twin plugged 3.4L Motronic
 

Guys,

I'm rebuilding my 3.2L Carrera into a reliable, street performance car. I'm sticking with Motronic for now but building so that I can go Carbs or ITBs down the road, with the understanding that I'll need to change camshafts when I do make that move.

I realize Motronic limits my camshaft options, but I'd like to what my options are. My goal is a reliable street rod that's also fun to drive at DE events. I've read that 964, 993ss (Daugherty) and Webcams 20/21 are popular options. How will these cams vary? Any other options I should consider?

Here's my build sheet:

Carrera Crank/Oil Pump/Case
Reconditioned/Balanced Carrera rods with ARP rod bolts
Mahle P&Cs - 98mm bore with 10.4:1 static compression - "RSR" - Hemi-shaped dome with double valve reliefs
Supertec Head Studs
Supertec-Rebuilt Cylinder Heads - twin plugged - titanium springs/retainers
964/993 twin plug distributor
Motronic Induction System with Andial Splitter
J&S Safeguard to handle knock
Steve Wong custom chip
993 Heat Exchangers with Flowmaster muffler

Thanks for your input.

That is the exact setup I have: I used his super cup cams from camgrinder.

Nice choice for the build.

Craig - What's the power delivery like on the super cup cams?

The original setting of 2.0mm overlap gave very good low end but less at 7k. John said to set it at 1.6mm and it keeps pulling up to 7k without a problem. Very nice engine. Mostly street but some track.

Do you know how these super cup cams compare to 3.2L carrera cams? Ideally, I'd like a cam that could pull strong up to 6500RPM and still be fun on the street.

That's what I'm going for :)

Emissions are not a concern, by the way.

It looks like the DC20, 993 Super Cup and 964 Super C2s are about the hottest cam I can reliably run on a street car having pistons with valve reliefs. Do any of these seem particularly well-suited for my setup?
