I have a hydraulic camshaft spec I call my Boss camshaft, it can be found elsewhere, specified as either a flat tappet or roller tappet camshaft. I have no experience with it in conjunction with 2V heads, but its a bad ass camshaft with 4V heads; 285°/295° duration and 60° overlap ground on 115° lsa. The big question is, will that spec give you the acceleration you're looking for? The motor will fry tires if you want it to, but it will hook up easier than a motor having a cam with narrower lsa. Motors with cams like this have a burbling idle due to the early opening exhaust valve ... as opposed to a lopey idle caused by a lot of overlap. The lobes I've selected for those cams are neither mild nor wild, they're hot but selected for longevity too. Of course, a 2V head can't use a lot of valve lift anyway. What made me think of this cam in the first place, it doesn't lift the valves any more than my Cobra Jet spec, but it has 10° more duration, which is what a motor with 2V heads needs to make more bhp.
Combine one of those Boss cams (flat or roller tappet) with a Parker 2V Funnelweb or a TFC 2V high rise manifold and a carb of about 700 CFM and your motor should be a screamer.
If you prefer a solid camshaft over a hydraulic cam, or if you prefer tighter lobe centers, let me know and we can explore that.

George, your Boss cam pattern was my first choice when I decided to rebuild and may go that way via the Crane 284 or Crower 284 cam. However I am considering a solid cam, mainly the CompCams 282S, so I'd welcome any thoughts you have on that one, or any other solid cam or cam profile.
