the rad will need swapped also with the shroud as the big block is a 3 or 4 core over the little one for the 6 cyl .

watch for drive shaft length . and the th400 is prob a 32 spline rear output for the drive shaft yoke over the 27 spline from the old drive-line combo .
I plan on lowering the truck a little, not slamming it. So i might be looking at replacing the front coils anyway. So i would need a new Yoke if i went with the th400 and maybe even a shorter drive shaft is what i am hearing?
