Well last year when I was at the drag strip,(I drive a 1/4 mile car that runns low 8s it is a 1973 vega with a 454) they had these little dragster called minins.They ran 5hp briggs and straton engines and ran 1/8 mile at about 60-70 mph. Any ways they ran exhaust header used thinner head gaskets shaved the head played with the carb and the big thing was the right gear ratio on the chain drive. They used racing fuel also I think they use 110 octan leaded fuel.[}]
