if you really want it...
you need a light aluminum v6, auto trans and something like a ford 9" rear end.

get busy with the plasma cutter, chop out enough of the firewall and trans tunnel to clear the engine and tranny. keep in mind to make room for the exhaust...

if you make it far enough to fit the engine and transmission, then modifying the rear end and getting a short drive shaft are easy.

people have put v6's in 210's before it's easier with a 510 and 240,260,280z's have a kit for a SBC

if the engine fits between the frame rails then you can put it in if you really want to.

learn to do this stuff yourself, you won't like paying someone else to do something like this.
