Dyno'ed My 360..it's a pig..what next?

You already have the Air Gap. I would address the heads. It sounds like your flow is poor. I have Comp's XE268 in my car with a 750 Eddy carb and some lightly worked J heads with 2.02s. I think you could easily hit 250 at the rear wheels without spending a bunch of money IF you can do your own work.
