Tranny switch. Advice please. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'll start this out by saying that it's my first post so I hope it turns out ok. I recently purchased a 72 c10 with a 350 and a 3 on the tree. I'm considering maybe wanting to switch it to a th-400. I'm not mechanically inept but it's been a number of years since I've done anything this in depth. Is this a hard switch to pull off? What all does the switch entail? Thanks.

Auto radiator w/cooler and lines
Auto starter
Driveline work
Th400 passing gear switch

Steering column(or floor shifter),crossmember change,speedo recalibrated,Driveshaft and yoke(i'm uncertain on lengths)?,tranny,swap flywheel to flexplate,tranny cooler,assorted hardware.This is probably not everything but is a start on all that needs to be dealt with.Keep in mind that the auto will work with the 3:73 rear gears but you mayt want to change.For the trouble and what it's worth,I would think about a 700R4 for the OD.
