Ok i have done some searches on here and haven't found exactly what i needed to know. OK i have a '71 long bed with a 350 and a 3 speed. going with newer 350 votec heads and TBI with 700r4. Is there a driveshaft i should start with thats one piece that would be close to being right,little or no modifications? out of a tahoe or sub?

I know a couple of local guys who are trying 1 piece shafts in longbeds but so far no luck just broken parts and a vibration thats kinda like an old ridged frame Harley.

Just curious but by not keep your 2 piece. I am putting in a rebuilt 700r4 when I get the down time. My local drive shaft shop said they would cut it down for me for lees than $50. I want to find another fron shaft so I can keep the turbo 350 as a spare.

probably will keep the 2 piece was just curious if it was possible since it doesn't seem to people are having good luck with it. Thanks for the replys guys.

if you read past articles,i asked about the 1 piece,as i have a 2 piece also......when you change out the tranny with the the 700r4, trl it to a driveshaft specialist and let them take the proper measurements, but you will have to notch the chassis where the carriar bearing is...........3 1/2 aluminum shaft w/ 700 yoke and new u-joints in springfield, roughly 250 bucks, this is the setup i'm going with, 1 piece shaft and 700r4.........

Pretty sure the 700r4 and turbo 350 yoke are the same. The price quoted was for cutting down my old drive shaft and re-using the yoke. Why would the carrier bearing need to be moved?
Thanks

ummm dont know if this helps, but i have a saginaw 4 speed and put a 1 piece in today out of a 73 chevy. it is a tad short, but i drove it to school at 65 and sounded GREAT. no more freaking carrier bearing rattle/squeak/noise. I was soooo happy

The 700R4 is the same length as a T350 with 9" tailshaft housing such as the ones found on '73-'81 longbed pickups. A shaft from one of those might be close. I think they're just shy of 71" from center to center of the U-joints.
