Hi Serge,

I've put those cams in four different engines. Two 3.3's, one 3.4, and one 3.6.

I was not the boss at the time and personally think the 964 cam is probably more than adequate for most 930's for all around performance

I don't remember all the details but here goes...

All with CIS injection. I can't remember all the port sizes but I remember one 3.3 had 36mm intake ports, the other 3 had 38mm. All had billet injector blocks to match.

I used cams from Webcam, they timed to 2.65mm lift on overlap.

They all had a fair amount of "cam lurch" which was an obnoxious violent pulsing when coasting below 1800 rpm, the cars w/ lightweight flywheel/clutch combos were really annoying...

Be prepared for your eyes to "tear up" anytime your checking the oil, and you may want a change of clothes after, from the fumes, this is with CO set for smoothest idle/low end possible.

One car had a prototype SSI exhaust w K27, the others had a short tube header config w/ the flat style collectors, not the best...

I think they all ran at least 7bar of CIS system pressure...
