Hey sky: yes the 6al will work fine but if you have a little extra money I would strongly recommend the digital 6+ because it has a nitrous retard. You should back the timing down about 2 degrees for every 50 hp you add. It also has 2 rev limiters and can be adjusted with a small screwdriver. I have mine mounted on the kick panel on the driver side so I can adjust it in the car, and no it does not get in the way of the clutch pedal.
BTW: do you have a fuel pressure cut off switch?
IF not I would recommend that too.
