I have a BBC with a demon carb and its running rich after one round of jetting down. it seems to stutter below 2k then takes off like a raped ape. any ways im looking for a suggestion of what to try next for jets.
there are 72's in the primarys and 85 in the secondarys i believe.

specs
402 block bored to 414
afr 305 heads
rpm air gap
11.0-1 CR
roller cam 236/242 .612.612 lift

and the carb is a demon 850
thanks for the pointers and if anymore info is needed let me know
