both of them are strong transmissions...in stock form, id actually go A833 over a T-10...but there is no aftermarket stronger gearsets for 833's like there are for T-10's (atleast not that i know of, or id buy a set)
we just built a Race Only 68 SS dart with a 471 Hemi (700hp/600tq) running low tens with an 833 crash box... it has liberty gears and some other goodies in it/done to it...
