My old school 340 upgrades and results.

Time for an update. Have upgraded a few minor items on the car and took it out to Bakersfield Raceway for Summit Series 1 and 2.
First change I have done is remove the mechanical fuel pump and installed a block off plate. Removed the factory 5/16 fuel line and installed aluminum 3/8 line along with AN fittings. A few months back I changed the slicks from 31×12 to 29x13. I also recently installed an Edelbrock performer rpm non air gap. Last time at the track with the factory intake manifold and 90 degree day car went a best 12.63. This time with cooler air mind you the car went 12.28 right off the trailer and ran consostant 12.30s all day.
Next morning things did not start out as smooth. Car sounded crisp and mean as I pulled into the burn out box. Did a hard burn out to start the day and as I pulled up to the lights the car died. Would not restart. I was pushed back out if the way and was told if I can get it started I can pull in at the end of the line for my class. Carb float was stuck down and fuel was flowing freely into the throttle bore. I tapped on the side of the carb and nothing helped. I told my wife to get the jeep to tow it back and when she left the carb stopped flowing fuel. I reached in hit the ignition switch and managed to start it. it was running rough but would rev up and the track official closed my hood and put my pins back in. I wad revving the motor while putting my helmet and belts back on. I did a short burn out and managed to stage the car. Launched hard cut a .006 light and ran a 12.18 at 109. Car never acted up the rest of the day.i went 2 rounds and list on a break out. First pass eliminations 12.28 on 12.25 dial. Next pass 12.32 on 12.30 dial. then lost with a 12.27 on a 12.33 dial in the heat of the day. broke out.
