two piece drive shaft

Hey need some help here, i have a 1969 C10 and i want to keep it a longbed truck, but heres my problem i don't know if the two piece drive shaft will hold up to my motor. Its a 383 stroker with TH350 trans.I just have the short block with forged internals for now. So before i continue the build i need some advice on what to do with the drive shaft setup as i can see it will be my weakest link. I'm aiming on my engine build for 450+HP and torque numbers. and maybe a little touch of the fast juice.

Re: two piece drive shaft

take them dowm to a driveshaft shop and have new made to handle 500+ horse they will replace your tubes with thicker wall meterial and will replace the U-joints with heavyer duty ones

Re: two piece drive shaft

as long as you have good U joints you'll be fine. A 2 piece is stronger than a real long one piece shaft.

Re: two piece drive shaft

Welcome to the board neighbor!

I agree with longhornman, keep the 2 piece. Get new u-joints and a poly carrier bearing, you will be good to go.

Re: two piece drive shaft

lmao carbon shaft, hit one thing and they explode. We build 1310 2" driveshafts for stock cars, we even drill a 1.5" hole in the middle of the weld yoke. No issues so far. I'd just make sure your shaft is in good condition and ballaned w good joints.

Re: two piece drive shaft

seen bone stock ones doing 12's in the 1/4 with slicks. Like said above, if the shaft is done properly, the 12 bolt will grenade first.
