Did you set the carb up before throwing it on there? I mean making sure the throttle screw was set barely open? Those dont have a return spring on them so if theyre not set right it'll stay open and do similar things.
You like to **** around with them or not? If you do then holley its where its at. Ive learned to like the holleys more these days but a good edelbrock 750 will do the job if you dont like messing around.

Keep and build the 6139 and sell the rest. That one was made for a 340. I’ve got a really nice one I’ve been saving to use on mine.
Good luck, I’m sure TQ masters will chime in.

That guy who is selling that for 800$ is a member on here. Tried buying something from me low and I told him I’d sell it for what he was asking for on eBay, needless to say he never bothered me again.
