I will pass along my thinking on the subject (it's free and you can ignor it if you want, ha ha ha)
Being that you are running a 383 I'm under the impression you won't be spinning it to the moon so I would think you would be happier with the broad range in power vs the peak #'s which is what I always tend to lean towards in choice.
The Extreme Energy cams give good #'s however they are harder on the valve line (traditionally) then the other series of cams. And I really don't think you need a dual pattern cam with those heads.
You have the cubic inches to step up a bit in cams and still be quite streetable. Richard mentioned the 280H Magnum (awsome cam, I'm running it now of course I have more stall and stiffer gears but less cubes) plug this stick into your computer and see the results. You should have lots of vac. for your brakes and I thought mine was going to be a lot lump pump pa pump pier than it is, you can tell it's cammed but not rank by anymeans.
Depending on your compression and quench (with your 67cc heads you should be able to be fairly tight) I can see you making 425 to 435 lbs of torque.
Hope this helps bud. Post your #'s when you get it plugged in. - Barry
