Valve Overlap

If the compression is really 12 to 1 like you said, you may not want to run more than 32 degrees with pump gas so it won't detonate when it gets hot in traffic. A batch of 108 or 110 octane & 35 degrees with 38s on that motor should have you in the 9s if you can keep the front end down & control wheelies! Ray.

On the street, I usually only have to really watch it in first. She usually breaks traction just enough to only float the front end in second. As far as fuel, I'm trying to keep it somewhat user friendly on 93 octane. I guess I could pump in some 105 to have a little fun on a poker run.

Keep an eye on those plugs. 140 seems a little small on the main and 50 is big on the pilot.
