Im not sure how i missed this thread as i was the one you called! Im glad to see you guys are getting "motivated" again!
I ordered a cam back in 09 for my slant motor from John, we talked a couple of times before we decided on specs. cam came with springs, 140 shipped as i recall. And what got me is it was at my door in two weeks. That cam is still in my 3200lbs slant car and its down to a 14.25 and can go faster!
The bad, as said it has the "old" lazy ramps, with 246* or duration at .050 and 282 Adv .465 after lash is pretty sad. As a cam grinder its your guys responsibility to know the engine your grinding cams for. It is well known the slants have a 1.4 rocker ratio, and the cams need to be ground and advertised accordingly.
Here is my 68. this is a easy 10:1 motor, runs on pump 91, and 101 leaded at the track, i was able to get 20mpg on a drive back and forth to vegas @ 65mph and 3000rpm (3.91 gear and 27" tire).
