I have Jim's 10mm cams in my 156 3.0 Auto. The idle is lumpy. Usable on a stock map, but not recommended.There are a few of us with his 10mm cam setup. Stock 3.0 with the 10mm cams can go from 230 bhp to 265 bhp. He tried it on a 147 3.0. Saabretooth has the10mm cams in a modified GT 3.2 and has 300 bhp. Most if not all of FWD car owners use the long runners which cut down top end power by quite a bit according to Jim's simulations. But the torque advantage is quite big for low rpm torque.
The 9.Xmm profile will net you less, maybe 250+ or so (not sure) but will be better for a road car.
I just purchased another 10mm set from him for my Alfa 75 3.2 race car. I can remap the Autronic ECU myself so idle is not going to be an issue. .
For road use, I'd recommend the 9.x mm Clio Williams cam profile. It's a lot better than the GTA(inlet)+stock(exhaust) combo performance wise.
