do any of you know if you can swap a 420a out and put a 4g63 motor bak in?is the mounting the same and the tranny? i have a guy that is coming out to look at a 4g63 block, he wants to put in the place of his 420a and i dont want to screw him over by selling an engine that is no use to him.

 

...you should know better than this... do a search man, and no one else should reply to this cause we dont need another thread about this...

 

tell him not to waste his time. Im suprised you havent seen this posted on the forums yet and knew. This is the most over played question on this site.
