your combo is very close to mine. I use a 1100 dominator on my 511 from Thumpercarbs and it's awesome on the street or track. It has .040 IFR's and .055 T-slots. PM me and i'll give ya the whole combo if your interested. The carb is so dosile with good street manners that you might think it has a 600 holley on it if ya didn't know better. This is a 2 circuit carb. It can set for hours and when i hit the start button, it fires to life and idles nice without touching the throttle. You might even think it was fuel injected.
