carb swap question
I want to swap out my carb on my '66 F100 352, the VIN say's it came with a 2bbl carb but somewhere along the way someone put a Motorcraft 4bbl carb on it. I just had the motor rebuilt and it was bored 30 over. I was told that this is a square bore intake and someone else said it's a spread bore, which is it ??
I bought a HOLLEY 4160 600cfm carb, (square bore), to install I want to know if I need to buy an adapter plate or will I be able to use the existing adapter plate to install this carb on the original intake ??
Thanks for the help as always

Check out the guys on the FE Block forum; I recently purchase a 65 model galaxie 500 352 engine with a 4 barrel; the intake is also a 4 barrel design; the trucks series where only 2 barrel intake / carb set ups. (On day will install it in my 65 truck)...
Hope this helps.

Not sure you can tell without pulling the carb off the intake. A spread bore has larger throttle plates in the rear, while a square bore has four throttle plates essentially the same size. If there is an aluminum spacer block under the carb, you can usually see the bump-out for the spread bore. Most cast iron factory intakes I've seen are square bore.
