Transmission ? on Inline 6

[brans72]

I was wondering if I might get some insight on this ? I have from you guys. I have a 67 C10 with a Inline 6 and 3 on the tree but wanna convert to automatic. I have a 350 automatic transmission and was wondering would it work and work correctly? I am not looking to build big power etc just be able to drive around ton and haul stuff with time to time. So will this work at all? Transmission came from 70 Chevelle and would be rebuilt first. Thanks in advance for any help/tips Brandon
