Aluminum 833OD behind a 440...your thoughts

I would not do so for an entirely different reason. I think, with 3.23 and the wide gearbox split "I" would be completely disappointed with performance.

"The formula" back then for the 69 383 RR, no options, jus' yer average RR was a 4 speed and 3.23. PERFECT gearing for general street use.
