Having not carried ours to the track yet (it ain't even on the dyno yet) I can't tell you what tech is accepting at the track, only what the rulebook and the blueprint sheet call out, and what the Holley tech guide says. The only person I know successfully running a fast L-88 in NHRA is Steve Calabro, maybe Steve will drop by and say what is on his car.

Again, I have SEEN vacuum secondary 850 carbs CLAIMED as correct for the 1969 427-430HP engines, and been told they are legal. The new looser rules on carbs MAY mean you can run either or, provided it is the correct size and model. Maybe Travis will check in again and give us another clarification.
