Until it breaks! LMAO It all depends on the internals of the transmission & how hard you are going to hammer it. Personally, I would use an aftermarket driveshaft. I know I do in my bracket car with 408 stroker, 904, rmvb, trans brake, & 5,000 dynamic converter on 29.5 x 10.5 slicks. SWAG on the 408 is 5-550 hp, I did crack the snout on one converter & dynamic made good on it.

if it has a manual valve body its not stock. depends on the quality of parts you are using.

Quality parts and a GOOD converter it'll take a lot of abuse..stock driveshaft not so much snapped the rear yoke and twisted mine,that's when I upgraded to a 3" custom w/1350 yokes
You should read up on drive shaft critical speed.I think there is a chart about it on mark Williams site.I have to admit i had no idea.Quality parts and a GOOD converter it'll take a lot of abuse..stock driveshaft not so much snapped the rear yoke and twisted mine,that's when I upgraded to a 3" custom w/1350 yokes

with a light car on street tires and stock suspension you are probably good to go.
you might not break parts until you start hooking with a heavy ride.

Who cares what stock will handle? Fill it with red eagles and kevlar bands and call it good!
My stock 904 (means all stock including VB) with the factory stock converter has been taking "occasional" abuse from a mild 360 in a A-body running 13's (now very low 13's) for the past few years with 2.45 gears and now 2.94 gears. Weight of vehicle, gears, and tire size makes a big difference on the life of the tranny as well. Same with DS.
