I did not go on the highway yet. It was midnight when we fired it up and 12:30 before the carb was adjusted and the timing right. We took it around the block a few times, but I was worried about cops being called so when we smoked the tires we did it mostly in the parking lot here. I did hit it hard a few times and brought it over 100 mph in about a block and a half and I wasn't all the way into the pedal. This thing is scary fast. I'm going to have to find some lonely, empty back roads to drive to get the feel of this beast. The timing is retarded to run on pump gas, so I don't have all the power it is capable of. I'm going to set up the time to get it to Tom's buddy soon and get it converted to E85 and take advantage of 105 octane. Man, another 7 or 8 degrees advanced timing? The power I am going to get is unbelievable.
