maki already answered you're question, and he knows a lot more about JUN cams than most of us

your springs and retainers will work just fine
the only difference is that jun retainers are titanium, i think ferrea are stainless steel

if your goal is 500hp+ go with 272's and 10.8lift
jun 264's are really similar to hks 272's in lift

Hay Guack007. Im not that sure really mate. The theory say that the more lift the better but too much and things get rough low down. With the pipers I would guess at the “ultimate road” cams for the road. These offer 11.5mm lift and 265 degrees duration so they are not too severe. Best to speak to your supplier or piper themselves. For the track or special stage then I would say the race cams. 12.0mm lift and 272degrees duration. They would be so cool in a road car hehe. Sorry I couldn’t be more specific.

Thanks Chris.

Thnx for the suggestions.
I think Im going to go with the Piper rally cam profiles (265 both 11.5mm both). The ultamate road cams you mentioned only have the 11.5 on the intake and not the exhaust. the exhaust is only 10.8 which is as bad as the HKS or JUN offerings usually are. Theres a thread titled " 11's Tonight " here:

Hes running anice setup with the Rally cams and said hed post a dyno graph soon. Then we can really see what these high lift cams can do =)
