Surging

This is the set up. 1971 440hp balanced, bluprinted, and gas ported. Elgin cam with hp specs. Torker II intake with a Mighty Demon 850. Mallory ignition, and a Unilight distributor. Notice no fuel filter. I'm ordering one today. I know, I'm a dumb@#$ for running without one. That may be the problem.:banghead:
