How complicated is it to swap a 426 crate hemi into a 1967 coronet 383 4-speed car? Is it necessary to change out the K-member and swap the 23 spline 4-speed for the 18 spline hemi 4-speed? The car has power steering but not power brakes.

Just get a set of Schumachers Hemi to stock V8 K frame mounts and it will bolt right in,assuming that the crate Hemi has standard Hemi mounting holes in the block. They did make early crate Hemi engines with the wedge type mounting ears too. I used the Schumacher mounts to bolt my crate Hemi into my 70 Charger R/T with no issues. They are nice sturdy mounts too.

You can reuse your existing 23 spline trans and clutch, just need a 8 bolt flywheel.
If you are using the large bell housing a special starter will be required.

FWIW, if you don't have a trans. , or are thinking about changing it, something with overdrive will be very beneficial.

Yep, I did the Schumacher Hemi mounts to 440 K-Frame conversion into my 70' Charger & everything was bolt in. Only had to ding my #1 Header tube to clear the power steering line & fitting.
