Thanks for all the good info and advice so far. The only other info that i can think of is weight is 4240 lbs with driver. Rear gears will be 3.23 for street/highway trips, and 3.91 for track. 8-3/4 rear. I will be running drag radials 28 “ tall.
Only actual numbers i have are dyno numbers. They are as follows:

So, peak torque is at 4500 rpm. Does that chang anything? I guess for strictly racing, i woukd want a 4500 stall, but for combo driving, what woukd you guys be looking for? Aside from calling and having one built, or my 10” adjusted. I will do that, but trying to understand the fundamentals and theory of it.
If i can think of any other info, ill add it
4240 lbs, 68 Charger in your signature ?? how did it get so heavy, mine has d60,a518 overdrive, A/C, everything there, glass hood,4050 with me. Get your converter looked at, I had to get a custom TIGHT 10" converter built for my 512 street car, will flash 4k, but drives good on the street 3.54 gear.
