Based in what you said, it still should be pretty lively........I hope.
More thoughts??

That's not a bad strategy. I consistently tended to overcam my motors early on, and it's almost never worth it.
A bigger HR cam for that motor would have 8 - 10 degrees more duration on a 110 or 112 LSA. Idle would become quite lumpy, and idle vacuum would drop to 10-12 inches - whether that's enough for A/C I can't say, but it's usually considered not enough for power brakes without a cannister or vacuum pump. Which, come to think of it, suggests that you should be able to plumb in a cannister and/or pump into the A/C vacuum supply as well to compensate for poor idle.
The HP estimates I gave you above might be a bit conservative, depending on how extensive the port job is on those Track 1s.
