77 C30 crew Dually trans swap questions

Currently the truck has a 454 paired to a TH350, my main question is what are your thoughts on putting a 700R4 behind the 454? Keeping in mind this is by no means a speed application, more for heavy loads and towing. The second question being more towards the drive shaft length, will I need to chop the shaft down? I will need a new yoke for sure if I am understanding it correctly (27 teeth vs 30 on the spline).
Thanks in advance for any input!
