is that an annular booster carb?

i believe it is a downleg booster style, but to be honest im not 100% sure how to check that...I dont think it is annular booster since i would have had to pay more for that i think, but it doesnt hurt to double check

Thats the same size primaryy and secondary jet and power valve on my holley 800 dp, on top of a 408 stroker, so yeah, you might be running a bit fat. What color is the smoke comming out of the pipes, blue/black, or white? hook a vacum gauge to the carb base plate, and find out what pv you need, kinda dependent on the cam in the motor.

so maybe i am running a bit fat then. My 340 is very mild comp 230 dur at .50 cam 480 lift single pattern, air gap, 1-5/8 headers to 3 inch xpipe exhaust, .30 over with stock heads, deep pan with tray, 3.91 gears

as far as the power valve goes, when hooked up to the vacuum gauge it looks like the pv i have is the appropriate size, but im just wondering since i felt that i have a rich condition and it seems like its overly sucking gas, so i thought it might be a possibility and wanted to see what you guys are running
