You would not lose anything if you modify the arm. It is a matter of mechanics. The motor will still do the same motion, the output is changed to compensate for the change of position. There is no need to change anything unless you want more clearance above the valve cover, as wiper motor clears the valve cover without modification. It is just close, and you must remove the wiper motor to remove the valve cover. Either way it seems like a good bit of work for minimal results.RatSSled,

One was a shoot from the hip, not been done, idea.
Take a good look at your firewall, do you see how you could rotate the motor 25-30 degrees counterclockwise?
Add to that, you would loose 30% of the park stroke.
If someone has successfully done this,,,, please,,,, lets see it.
Engine in, while ours differ in fat block vs ls,
