4BBL Scout IIs came stock with Carter Thermoquad carbs. Holleys were on square bore 392s in the bigger trucks.

There are 100's of different Holley carbs. Give us the LIST number found on the air horn so we can look up what you've got. I'm running LIST 8007 390cfm square bore carb on my Scout's 345.

Look up my thread on tuning this carb. Search 8007. It's all there.
