Jacks: 69 cuda fastback

well i did some work today on the new intake and carb. My friend was discussing holley carbs with me and mentioned that people put mettering blocks on the secondaries of the carb i have this allows them to change gets as apposed to drilling holes in the secondary fuel holes, sounded like a good idea to me and he has an extra carb same as i have laying around, tomorrow im going to dip the carb so its all clean.
