edelbrock Mopar throttle adapter #1481. $9.97 at Summitt. There's an AFB #4131S for $100 in the for sale section here which iirc is correct for a 66 HP 440. I have 2 of em (4131S) on a dual quad "B" single plane '58 iron intake going on a 451



Technically speaking there was no "HP" 440 in 1966, just the "TNT" 440 for the Chrysler 300's etc. 1966's were a very different engine as compared to a 67 HP, smaller port heads, low rise intake, log style exhaust manifolds, etc. made the first year 440 basically nothing more than a bored out 413. The 4131 carb was the same one used on many of the mundane small valve head/LP 1966 383/413/440 engines, there was nothing "HP" about them in the least.

So, while the 4131 carb will work fine, a correct 67 carb (both being in stock form) will be a better unit more suited for a true 67 HP engine. An Edelbrock will also work fine but be sure to do a price check before just ordering a new carb, used originals rebuilt/restored are usually competitively priced and will always be worth more later if you decide to sell.
