[Chevelle-list] Driveshaft replacement?

[Don Allen]

Hi everyone!  I have a 1969 Chevelle and I am replacing the 6 cyl., 
3speed saginaw and 10 bolt rear with a 396 cid, 4 speed muncie and a 12 
bolt posi rear.  My question is, does anyone know if my original 
driveshaft will be strong enough to handle the new HP or do I need to 
start looking for a new driveshaft?  Thanks in advance!
