It will definitely be an improvement.
Keep in mind the LD4B has no coil mount provision but you can use a 6pack coil bracket. That's what I used. Also get a proper socket adapter for the torque wrench when tightening bolts by carb plenum.
I am looking for an Edlebrock LD4B for my 273. It's a 66 2bbl "hipo-ized" with a cam and cast iron 4 bbl manifold. 4 sp. Does anyone have an LD4B for sale? Do you think it would make much of a difference?View attachment 1715125431
