Will my 8-3/4 hold up behind a 4 speed?

hey scott, thanks for the info, and yes i am still wet behind the ears in the manual world lol...I will be upgrading to the larger u joint (think its 7620 or something if im im not mistaken)...unfortunatly i cant remember if i have the clutch type or cone type pod...and my pod is also a used one too, which like you said you never know what it went through before....but if im going to chance toasting the rearend by only going into the high 12's, then maybe the 8-3/4 isnt enough? dangit this isnt cool
