What will it run?

I did a burnout the first couple runs, then realized I did not need to. lol. I'm sure if I spent enough time on it and threw the gauge on it, I could get it to do what I want, but the end result is I am trying to use a 800+cfm carb on a 8:1 273 that has a single plane, and way too tall of gear. I think I will be miles ahead throwing on a carb that more matches the size of the motor. Timing curve is 16 intial, 36 total in by 2k. Not sure what you mean by the polyglass comment? I have gone 1.54 on g70-14's... lol
