The second design l88 in 1969 went to a 850 double pumper. The list number was 4296. It and the list 4295 carb used on the 1969 z28 crossram were the first double pumpers made by Holley. It was a turning point in Holley performance.

The 3418 was a vacuum secondary carb, then in 69 they changed to a 4296, which was a double pumper. Just for the record, I have never run across a plain 3418, only 3418-1's. Strange.
