My 60' was 3.1. I can contribute most of the slow time to my inexperience, I was spinning bad off the line, so I shifted into second, that dis not help, I hit my shift point and grabbed third and bogged. I am not 100% sure if the secondaries are opening, some how I do not think so. But I have since removed 1/4" of carb space, turned the carb to push pull instead of sideways. Right now the car peters out at about 4500RPM. The engine is a 250, it is from a 1970 Blazer, according to the casting numbers, compression is good. My timing may have been retarded, I have since do a lot of tuning and stuff, so I am not sure where it will be this year, if I can get it to the track, I am waiting on neck surgery and do not know when it will be. I know with zero more tuning and a driver that can drive better than me I know the time will be much better and the MPH will be there.
