Am I Going To Be Happy With This Camshaft?

That's more than a little interesting! Is the pushrod cup lower in the lifter body to offset for that? I'll have to look through my original parts when I get a chance, I think I have some used factory lifters like that, too, from a couple of 1973-1974 360's. Just curious, did you and Ken decide to go with the similar 487 cam or did Ken steer you in a different direction? He has some other fairly fast rate hydraulics that looked like they also would have worked well for your application.
