Another flywheel question

I like YRs thinking,
and banging gears with an aluminum FW,and 4.30s is a hoot.
But you have 3.54s:
With a starter gear of just 3.54x2.66=9.44 and say 28s, your effective gear is just 8.09 corrected to a 12" radius. IDK about your blown 408, but my little NA 367 makes a lotta low rpm torque, with over 185psi cylinder pressure, and it did not like that meager TM;(edit; TM=TorqueMultiplication) even with a heavy steel flywheel.
So I increased my starter to 9.75 corrected, which is 20% more TM. Now it's almost a dump it and go deal. Blip the throttle and almost dump it, letting the flywheel do the work.( EDIT; you can increase TM either with rear gear or with trans gear, the engine won't know the difference in first gear. I did it with a 3.09 low, because I wanted to keep the 3.55s in the back, for hiway cruising. But you could just as well keep the 2.66 low of the standard A833, and install a bigger number rear gear.This will of course increase your cruise rpm. Another thing a bigger rear gear will do, is bring your shift mphs down, at the same shift rpm. This condenses your run and increases your average power over distance, which for a small engine is kindof important. For a blown 408 Ima thinking not so much,lol.)
With street tires, you will never need to rev that stroker up, to launch, cuz there's just no traction, not even with just 400hp, not even with 325/50-15 BFG-DRs. (EDIT;What I mean is, for me at least, the 367 just spins at drop of a hat with the 9.75 corrected TM, with those tires listed. And it will even initiate a spin to well past 40 mph in second gear. And that is just a NA367 with a 230* cam and Eddies.)
So, IMO, you might as well not sound like a Mustang, and just keep the heavier FW, for the Mopar-is-king-of-grunt takeoffs.
Blip,dump,chirp, and gone.
IDK how heavy my FW is. It's out of an old 340 car, rebalanced for my 360. I'd guess probably close to 30#.
Besides, if you don't like it it only takes 17 minutes to take the trans down, and that includes taking the GVOD down first, and the dual 3" TTI system from the collectors to the muffs. And unless you run a scattershield....maybe 10 more to see the FW on the floor.
But I know you'll get to really like that 30 pounder on the street.
Blip,dump,chirp, and gone.
Just my opinion.
EDIT; but I get YRs comment on the 4 inch crank, and if I had one,and a blower, I'd be tempted to try a lighter FW. But Like I said, I know nothing about driving a blower engine.
