it looks as if its just the hole opening that has been opened up so carburators with bigger throttle plates will fit, it looks as if the factory 2 barrel will still bolt on
Yep a stock carb will fit and work just like normal. In fact the PO of this manifold had used a bbd with it with no issues. Anyone familiar with slantsix.org will know the vehicle this came off of; the Slantkota,a slant six powered dakota.
Ive got it back up on ebay with a longer duration,hope I have better luck this time!
