I'm having my 73 LeSabre outfitted with dual exausts. Eventually I want to swap 2bbl carb with 4bbl. Tips and suggestions? Btw, I'm NOT doing headers. Thanks in advance!

Use TA Performance single plane. I’ve got one on my 350 and I like it a lot. The 350 seems to like more carburetor than it should. I’m running an electric choke 840 cfm Q-jet with no issues.
