turbo 350 to 700 r4
 

hi guys i own a 1968 chev truck and i am wanting to convert the turbo 350 to a 700 r4 the truck has a two piece driveshaft i was wondering do i have to change the tailshaft on the 700 r4 to fit for the two piece driveshaft any help would be great thank you

I'm in the process of doing the same on my '70. I have a turbo 350 with a long tail shaft housing, after measuring everything it looks like my driveshaft is going to work. ( I had shortened it previously, when I changed the transmission to the long tail shaft ) The 700R4 transmission tails haft will work but you may have to short your driveshaft.

I'm sure someone else will chime in. But the long tailshaft on the 350 should be about 6" if it's the short tail shaft you'll have to shorten your driveshaft by 3" or so. Measure twice and have it made once. Perfect time to go to a one piece drive shaft.

I have been told that a long tails haft 350 will be a direct fit except moving the trans mount back a little. I have a 700 on my bench to put in my 69 in the next couple of weeks. I will let you know how that turns out if you are not in a big hurry.
