Got a tech question for all you zheads out there
What im trying to do is this find a cam to work with my car I checked with Jun Auto from Japan this is what they sent me ....

2: 296 deg .331 Lift
3: 300 deg .382 Lift
4: 304 deg .335 Lift
5: 312 deg .354 Lift
6: 312 deg .339 Lift
7: 316 deg .366 Lift
8: 316 deg .417 Lift

the price is $809.00 and can be purchased through any Jun dealer.....

www.junusa.com
web site.......

What I can make out is center Lobe is at 110

Im used to seeing some thing like example:
Duration-Lift-center
Question I got is how do I figure Degree to Duration so I can get a camshaft Grounded Instead of paying 809.00 for a camshaft Yes I typed It right....
any advice please Help

Thank you
Ron

I have done some basic work on camshaft design I can tell you that there is a little more to it than just these two numbers such as heel base circle etc. These are secrets that no one is supposed to know about, and is not avalable on the spec sheet . These other things eliminate valve float spring binding excessive wear . You can measure and copy by carefully recording heights at a given angle . Then you have to probably get the custom springs from them any way, the cam was designed for these springs in the first place . If you aren't pushing more than 400 hp a turbo cam especially this price will probably be dissapointing . It might have a little more jam in upper rpms . Spend that $800 on upgrading turbo, intercooler, forged pistons .
