Took the 66 out today and noticed I,ve got some surging going on while crusing?Car idles great,goes when hitting the go fast peddle.It seems while cruising I,m not getting enough fuel?Could this be my timing?Air fuel mixture?Has anybody had this problem?I did backoff the timing while out at the track Wed.nite,dropped 1/2 a second.Thanks for any help!It,s a thermoquad and I just got a Holley 750 v.s for backup.Motor,s a 360,mild cam.
