I seriously recommend taking it in and getting it tuned on a dyno, but before you go, you want to track down more jets or make sure the shop has parts and knows how to tune old school.

Sadly, most shops hate dyno tuning carbies because it is so labour intensive.

 

I can tell you that on my Edelbrock 650cfm carby fed 13B bridgeport, I have spent a grand on dyno tuning because there is no data for the conversion, and I can still get more power with more

development and dyno time.
