What cam would you buy?

2nd the Lunati Voodoo.

The purple cam grinds were good for their time, but there's much better performing cams out there now (like Lunati's VooDoo series).

Question though, there's a big performance jump between the purple cam you listed and the 10200703, that lunati cam is quite a bit hotter. The 10200702 is much closer in performance to the purple cam you picked out, and still a better choice than the purple cam.

That said, the 10200703 is still a very streetable cam. I have that very cam in the 318 I'm building for my EL5 Dart, with a set of RHS heads.
