Just wanted to post some feedback. Carb I ordered was a #6324, 850 CFM originally off a 73 440. The 6324 is what I got. Overall finish was nice & clean. I stripped the carb to check the innards. Float levels were off, but that could have happened in shipping. It had the wrong pri jets & rods for 6324. They fitted slightly smaller jets & thinner rods to bring the metering areas back close to original, so not too worried about that because carb is going on a 600 hp engine & will likely need jetting changes. Overall, quite pleased & would buy another one. Gave it 8 out of 10.
