Victor Jr or Super Victor carb intake for a 6800-7000 rpm 331

I keep debating between a Vic Jr or a Super victor on this carbed combo: Which one would you use?
Mexican block 331
11.5-1
11R190 heads
custom cam 239/248, .600"/.600", 110 sep.
1 3/4 longtubes/ 3" exhaust dumped
Faceplated TKO 600
4.30 gear with 27 1/2" DR's
Shift point of 6800-7000
It is a street strip with not a lot of street miles per year
I did some searching and it is confusing. Some say the Super victor is too large and others say the Super Victor has longer runners since it is taller and has more even distribution to the cylinders which makes the super the better choice, but others swear by the vic jr. so I don't know what to think.
Any advice is appreciated
Thanks!

This is the question that never gets a straight answer.

Obvious players are super, jr and air gap.

I would think with your combo, the super would be the way to go, but I would love to see how a max effort air gap or rpm compare.

I’m running a mildly ported jr on a z headed 363 which is set up very mild in a fairmont wagon. I’m guessing 3400 to 3500 with me in it. I’ve got some more tuning to do, but the traps correct to 118.5 with shorty headers, mild stall and 3.55’s. Max power per ford is supposed to be 6500, but it wants to rev higher. I will get the 4.10’s installed and see how that does and then will have my rpm ported for a comparison.
