1996 pontiac grand am single ohc to dual ohc engine swap?

[Moose]

I have a 1996 pontiac grand am with a single ohc engine number 3 cylinder has no compression. I am going to put a new engine in it and was wondering if I could put the dual ohc i4 in place of the single ohc engine?
4 cylinder to 4 cylinder would I need to change the computer or wiring harness?I know the engine will fit and bolt up I'm just unsure of the harness and computer differences.

yes you can put in the quad, but your nuts its even harder to work on than the sohc anyway i think its a quad or does it only have 2 valves per cylinder.its basically the same engine till you get to the head i think.
