no it wont maybe if you spent massive amounts of money to redo engine mounts and everything else.

No unfortunately it will not work.
The engine mounts are different. The axles are different. The fuel delivery system is different (F.I to carb). The complete electrical is different. The exhaust is different.
Pretty much everything is different.
