How to tell the difference between a 420a and a 4g63
I have a motor from fourstar engine and i cant call because they went out of bussiness. I have no clue what kind of motor it is. I know that it is for an eclipse, but how do i tell the difference between a 420a and a 4g63?
420A

4G63

Notice how the air intake is on the left side of a 4g63, and right side of 420a
