Trans Question

[steelhorse]

I am trying to decide which direction to go with my daughters 67 c10.It currently is a long step 6cyl with a 3 on the tree.I am defently going to add power brakes(disc) and steering.I am either going to chop or replace the frame and will probably go with an automatic(less distractions for a 16 year old)What I am wondering is will a turbo 350 or 700r4 bolt behind the 6cyl?Sorry no pics yet,this was her great grandfathers truck bought new in 67 and will be a family project till she gets her license(3yrs)
