Default '62 Catalina Tri-Power Install

I am looking to do a few upgrades to the stock 389, 15H with a 2bbl. Car is a solid ‘62 2dr Catalina with a slim-jim & 2.69 gears. Planning to replace the trans with a TH400, add tripower, new cam & lifters, new valve springs & anything else that needs replacement. Since the car will be a cruiser and not a race car I am looking at the “744” cam from Melling. Have a guy in Ohio putting together a tri-power setup & he is asking for jet sizes. Thought I would start with 60’s in the center & 66’s on the end carbs. What do you guys think about the cam selection & jet sizes?

Be aware that I would love to build up a 455 coupled to a 700R4 & 3:42 gears but I have not won the lottery yet.
