6 speed drivetrain strength with high HP
I’ve done some searching and it seems the U Joints and halfshafts are the weak links in the drivetrain. With steel halfshafts and solid U joints, does anyone have any feedback on what a safe RWHP limit is? Not talking dragstrip use but hard street use. Anyone with 383’s and blowers? Thanks

With real street tires and a single disk clutch, and driving that doesn't resemble the breaking of an anvil....I don't think that there is a practical limit to the drivetrain's strength, as the tires should spin before parts break, and a single disk should soften the blows...some.
It's hooking tires and hammering with a hard biting clutch....with a dual disk and sticky tires, you could break **** w/300 hp.

Oh!....you want to know how much power, using 314 drag radials! I didn't see that in your first post. Depends on how hard you "hit" the drive train with whatever power you have. With a dual disk and sticky tires, you could break **** w/300 hp. Is that answer better? 
rklessdriver and TPI421vette both have run high hp cars with 6 speeds with drag radial and/or slicks....they've broken every part that you can break, over the years. Dizwiz is running a supercharger and nitrous on real street tire and hasn't broken anything. Maybe they can provide an answer that you'll like better?
