Without reading anything except the first two posts...
Edelbrock is not making the intake anymore.
Holley carbs can be purchased at Holley.com
The 340’s rear carb has a tab in the passenger side barrel for fuel distribution but not on any other carb.
I myself have a mix of carbs for my set up since it will be a stroker of 400+ cubic inches.
The other differences in the carbs is jetting.
(I just read the entire post.)
A FI 6 pack is an interesting idea. There are several companies to choose from.
I was lucky because I found a dealership going out of biz. They were selling all of there stock stupid cheap just to get rid of it. Have a bank roll ready to press “Buy now” just incase you roll across something to go to pass up but make it as nice of a part as possible since rebuilding carbs is expensive and intakes have tripled in price if not more. SB 6 pack intakes are the new MoPar gold.
The other ridiculous cost is the air cleaner base. I purchased a fiberglass unit that wasn’t worth the price but to fix it was cheap and easy to a degree a 5th grader could do it nicely. Use the K&N filter because the paper air filter is also a Gold and Platinum encrusted item.
