It would be interesting to see just where the tq peak occurs, and how big the number is.
The combo looks to me like it would be best suited towards a dragster, or another pretty light car with a trans brake.
A RB451 I built with MW port SR’s that flowed noticeably less than the OP’s Victors, 13:1cr, Indy 440-3, 1050 carb, a cam about 10deg smaller with .650 lift and my dyno headers made 712hp@7200. Peak tq was at 5500.......right about 600ft/lbs.
Found the sheet:
