aluminum driveshaft or steel DS with 347?

[Sevan]

Does anyone know how much HP/Torque an aluminum driveshaft can handle? I putting in a 347 soon and would like to know if I need to use my steel one or not.

Thanks

I know peeps who run 9s on FRPP aluminum drive shaft with stock u joints. On diff note I know people who have twizzled steel shafts/1350 u joints with 12 second mustangs..I am going to be running aluminum shaft should work fine as stated above...

i always thought the aluminum ones were stronger

I think the alum. ones are stronger as well.

smr, good to hear that people runnin 9s have no issuses with alum. ds...i'll just pickup a ds loop just to be on the safe side....thanks guys

I dont know if its stronger or not. But I know its bigger in diameter. Could cause clearance issues with exhaust, etc., Also the only reason I ever seen people get them......was because they had vibrations while driving after new gears. The aluminum driveshaft seemed to fix it for them.

dont have any exhaust issuses or vibrartion at all

well i have never heard of ne1 getting big gains in the quarter from just an alum ds. but with your mods. a alum ds and flywheel. would help your 347 get into the higher rpms alot faster. where it really makes power at.
