Because of the water leak, I never got a good pull. I was triyng to test a dual quad vs a single dominator vs the 8 carb X3. It took A LOT of messing around just to get it to run on the 8 carbs. I started out so lean, it wouldn't do anything more than idle. There really is no info out there on where to start with this old obsolete stuff. After it was running good and broke in and checked out, and we started trying get some good pulls, the leaking happened. So as of now, it still isn't properly dyno tuned.
