700r4 swap questions

[NEWFISHER]

I'm getting ready to swap the motor/trans and rear axle assembly out from under my 1950 Suburban. Removing a later model 250 hei, single carb, stock manifolds set up, a sm465 granny low 4speed and the ( apparently rare dana) rear axle assembly with 3:08's . I'm installing another fully built ( bored, milled, cammed, 6=8 with a Holley) 250, an MD8 cased 700r4 and a 10 bolt rear axle from a 68' 2x with 3:73's and posi.

My question(s) to those who have done the 700r4 swap:

*Speedo cable from the 1950, will it screw into the 700r4? If not waht cable/adapter have you used?

*What are you guys doing for lock up? This is what I was thinking: http://www.jalopyjournal.com/forum/s...ighlight=700r4

*Are the inline dual pass oil coolers worth using? Thoughts are to mount it on the frame rail near the trans

Thanks guys and gals
