Ok need to know correct # for 1965 327 holley,have looked it up but come up with a few different #'s Would 2818-1 with a 521 Date code be correct ?
The 2818-1 is correct for a 350/365 hp, and the date comes up the first week in February, 1965. The Cheverolet by the Numbers books are great for stuff like this.
