Car has always flown in the 60'. Its is a Muscle Motors 474 w/an Ultra-Dyne .613" flat tappet cam. Turbo 400 trans w/Rossler brake. Dana 60 4.88 gears & 31" x 14" tires. Car weigh 3060 dry& I'm about 270#. Don't know why it runs the 60 so fast. Shift both at 6600 go thru the traps right at 7000. Have went 1.29 60' twice. Thanks, Ken
