Carb recommendations for my 340

My 81 w150 came from the factory with the 318 and a TQ. I loved that combo. Had 3.21s and I put 32x11.50-15s on it...I also had an 89 diplomat that came with a QJ and I had all kinds of problems with that one til I swapped it out. I originally swapped it for a new, identical factory spec QJ and it took was crap but in different ways. It wasn't til I put a Carterbrock on that car that it started running like I expected.
I didn't have access to a TQ at that time for whatever reason
