Quality of the question’s determines the quality of the response. Hence: limited question, limited response. Just for reference.

It can be done, but the transmission will need to be built to handle it.

Wide band, new rev drum, sonnax od servo, pin leak addressed, 4th accum blocked . large servo feed hole .093 or larger. 220 to 230 max line at WOT and yes, But will still be hard on the band, its a big jump right at 30 percent, And more with wind resistance of the car will be about like having a car that weighs 2x as much . But yes can be done , I would not suggest it daily and a solid 3-4 clutch set up also a must as those frictions while already applied have to hold all of that too, I would say an 8 friction and no leaks in the 3-4 hyd.
But even with all of that I would not suggest it regularly unless you are reared really low like 4.11 4.56
