I brought it to a trusted friend who works on strip cars. He owns the same shop in the same location that his Dad owned in the 60's. Anyhow, he called me up and told me that my motor mount was broken on "the torque side of the motor" and when I accelerated the motor was lifting against the throttle linkage and shutting the carbs down. He fixed the mount along with the kickdown switch in the tranny!
HOLY CRAP! Is this what a 400 is supposed to be like? I held on for my life during his test drive and was amazed when the car chirped the tires from 1st to 2nd gear. From cruising speed as I punched it, it fell into gear smoothly and PULLED HARD!
I took my wife for a ride when she got home from work and I punched it from a dead stop! NO BOG AT ALL! After the 20+ feet of rubber deposit, the car launched like never before.
