Sounds like a good healthy street cam with that lift. My A15 cam is a pretty tame Delta Cams regrind .229 duration @ .050" and .414" lift. I think advertised duration is around 260 or something, can't remember. With a balanced engine, stock single valve springs, and Weber 32/36 DGV it redlined at 7800 rpm. It has barely any lope to it and idles smooth. Power band on mine is from about 3500-redline. I've been thinking I need more cam, but I think mine is actually pretty good for the turbo/EFI I'm gonna attempt soon. Good luck

The number 82 has 0.370" lift with 276 degrees nominal duration and 212 degrees @ 0.050 lift. A nice torquey little number that provides lots of bottom grunt with a good top end to around 7000 but can run a bit higher. Its advantage is it has more grunt in the 3500 -7000 range

Its a huge valve lift, but the duration doesn't seem all that big. If anyone's interested, have a look at the "Geo. Wade Camshaft Engineering" page, but remember that the cams shown are for BMC Sprites with a rocker ratio of about 1.27:1 which is much lower that the Datto 1.4:1, so the lift at the valve will be more than shown on the page.
A good street cam and one I know works is the Wade 169---it will run all the way thro to 7000 with only a slighly lumpy idle.
