Usually an indiction of too lean or not enough timing.
I'd reckon you'd want at least 16 initial with no more than abt 34 0f total with your combo.
Try some lighter metering rod springs.Yellows should be good.
Might be a bit much carb bt the 3.91s should help to overcome that.
If the carb is too big the bogginess will be caused by the secondaries opening too early and unfortuneately it's a messy and difficult job to delay them on a performer unlike a thunder which is adjustable in the secondaries.
A bandaid solution to overcome it is to up the jetting to get over the leanness caused by the secondaries opening too early.
Theory being that with secondaries opening too early you have a poor vacuum signal to draw enough fuel so you overjet to compensate.
Just my thoughts on how to make what you've got work.
