Diffrance between 83-84

So I picked up a parts bike today and didn't realize 83 was a 750 and 84 was a 700. Am I going to have any problems putting the 700 in too the 750's frame. What are the major differences?

 

It is all in the crankshaft stroke, everything else is the same aside from paint.

 

Now the difference between diffrance and difference is quite clear.

 

Dam the no spell check in the title gets me every time

 

I have a few other questions and concerns but I need to up load the pics first.
