Allan,
The "little" Edelbrock is a great choice for a mild 260/289. I have had
a 1403 (electric choke version) on one of my cars for seven years
without issues. I wound up changing the needle and spring combination on
the primaries and one step smaller jets in the secondaries to lean it
out slightly. Your engine may/will have different needs, especially if
you have tubular headers and a lumpy cam. I like them so much I just
bought a 1406 (600 CFM Electric choke) carb for my stroker project.
Buy the tuning calibration kit (part # 1486), it has all you need to get
the mixture dialed in. The stock SU fuel pump is marginal for this size
carb, I could drain the bowls on a hard third/fourth gear pull. I
switched to a Holley Red Head fuel pump and that cured the delivery
issue.
Be sure to carefully check your stack-up height with your new manifold,
some engine mounts are taller than others and with a F4B in place your
air cleaner might be interfering with the hood. Swipe some Playdoh from
the brat next door, put a ball of it onto the air cleaner and carefully
close your hood. You need a minimum of 1/4" clearance, more is better. I
had to go to a flathead screw for my air cleaner to gain enough room.
Have fun, go fast!

Thanks everyone.
I had planned to install a 4 bbl on a F4B manifold this winter but since
the Holly 2 bbl became a problem, I moved up the 4 bbl installation
to...next week.
I went by Summit Racing and picked up an Eldebrock Performance Carb,
model
1404 with manual choke
and delivers 500 cfm.
The carb is new not remanufactured so it ought to work, right?
I am also moving the coil from the factory location on top of the intake
manifold near the gas line, to a cooler and safer location near the
generator.
Thanks again for your help,
Allan
