Your plan will work out just fine, and what you're shooting for is a very solid 11 second kind of a street/strip deal.

My '69 GTX is a getting little bit dated but still runs well and is along the same lines.

451ci (400 B engine based, but really close enough to a .055 or .060 over 440 for comparison sake)
10.75:1
RPM heads, minor prep (backcut valves, blended port openings slightly)
PRH/Comp .630/262-266 solid roller
Victor 383 intake prepped at home, 1000/4150 race demon
2" supercomps/mufflers/X pipe exhaust I fabbed in my Dad's driveway

The converter I have is somewhat "wrong" for the combination, it was originally made for a 572 Wedge
A body race application, and is too tight for mine for racing but it drives really nice on the street so I've left it alone.

4.10 Dana with a Power Lock.

Most of the time it went 11.20s and 11.30s around 120.
11.0 @ 123 best ever (three times same day) and for whatever reason I haven't been able to do it again.

Peak power rpm is about 6200/chassis dyno, pretty close to what you were looking for.

Later I tried a 950 Quick Fuel Brawler and it ran about the same ET as before
but feels quite a bit snappier on the street. Only had it to the track once with that carb
and it went 7.15, 7.16, 7.17, 7.17 that day (so basically 11-teens to 20s).

TBH the only outdated item you're thinking about is the M1, and it's still a pretty darn good piece.
I'm sure a TFS or prepped Victor would pick up a little bit but nothing earth shattering.

It wasn't long after this shot we had to intall a roll bar. You will too! Good luck
