Couple of items stand out to me:
You will never be much below 4000 on the track
A stroker RB built big CR will have way more low end torque than you will ever be able to put to the track
You will actually want to use the cam choice to dial back the torque, and move the power band upwards
Almost all overtaking will be at the top end, before braking, if you are passing anybody exiting a corner, they are a dog to begin with
If you are running just against the clock, no overtaking, you can lower your power curve a tad.
I'm seeing comments from folks that have obviously never road raced a big block mopar. Probably a few that haven't road raced at all.
If you want this engine to last, you'll want to keep it stock bore/stroke and put a good mild roller cam that pulls to 6500rpm tops. Get the heads and induction to support the cam and breathe well. You shouldn't need more than 450-500hp to the ground, beyond that and you'll start having driveline AND chassis reliability issues. We tried the 7500rpm dopey motor and it was stupid. We tossed that cam after 1 race.
If properly geared, you'll be setting the car to hit peak RPM in 4th gear on the fastest part of the track. That'll put you in 3rd or 4th most of the way around most tracks from 2500-5000 rpms most of the time and to red line MAYBE 5-6 times in a lap. You lose an amazing amount of time per lap shifting. Unless you have a paddle shifted 8 speed, try to not shift. We have the advantage of torque. You'll need wicked brakes and the low end to grunt out of the corners most lighter cars can finesse their way through. It gives you the advantage of running different lines that can catch other drivers off guard.
