Stock Alty cam specs...
Just some info I got from talking w/Harry again at BYP...The Altima's stock cam duration is around 212deg. w/around a 9mm lift...They offer a welded/machined set for $450-242duration and around 10mm lift-same process as Web cams (well known comp)and w/10:1 comp or more, at least 20whp on top of your basic bolt ons and I believe them-and that doesn't include any porting/polishing-it wouldn't hurt but they say the stock head (as verified by Modified Mag)flows very well, in fact, according to Mod. Mag, flows around 240cc vs 260cc for a VTEC honda head...
BTW, these really need upgraded springs to be completely safe and since the added material is welded on and machined, no changing of shims needed....
