Driveshaft for 600hp 4sp ?

mbaird said
I need to order a driveshaft for this build and would like some feedback . I want one that is stout enough but not overkill.

69 Swinger 4sp
408 with Ported W2s and solid roller
( could very well push 600hp)
McLeod RST clutch
20lb SFI McLeod flywheel
8 3/4 braced

The car will be mostly street driven with a few runs per year.
I am thinking 3" chrome moly and 1350 joints.....

What's wrong with going a little over kill...........drive shaft failure is not something to be put down the list of priorities to be worried about.........about the time you have one come up thru the floor it will change your perspective dramatically...........**** happens fast do your best to avoid it
