There is a weight savings there but I'm not sure I'd go to the trouble and expense to save it. Much easier to remove the strut tower brace if you are running it, the weights are comparable.
In principal if I were required to run a rev limiter I would, I actually considered it when swapping to the carb set up, but it would add a component that could cause engine failure at some point so I'd very much prefer not to.
I think the over riding question is why require a rev limiter. Aaron makes some very valid points; anything past an RPM around 5600-5800 is on a declining torque curve; and revs within the torque curve can be managed by rear end gear ratio to the track.
I had some close races with other mustangs and 4th gens, I see no performance advantage to running a carb. Arguably I'm giving away some torq.
I think this RCR does not address a real issue.
Likely in your particular situation, it wouldn't make a difference to have a rev limit, which likely is the case for many.
However, if someone (already been done) built some very solid internals (no one ever checks), ran a low rear gear (3.08-3.23 ish), and rev'd the snot out of the car, they would:
Eliminate several shifts per lap.
Provide additional options to shift or not shift, depending on circumstances.
Be able to hold a gear in various situations, including: a particular section where most need to shift, and off line while racing hard.
All of which is an advantage over all other cars with limits.
Again the whole point of the class is to keep it simple and cost effective. This closes a loop hole for spending big money to gain an advantage. And to answer the question ...again. Yes this has already worked as an advantage......and yes on a big stage. And likely someone else will in future. And no....its not killing the entire class, but whats wrong with getting items figured out before they become a big deal...again ?
