I agree with you on what you said above.
But in 69 383 A/C,Automatic Used Holley Carbs #R4440(4160 series)
They did NOT use the Holley carbs in 68.
They also used Holley in 1970 with the N/96 and N96+n95
And 71
I do not know why they did this. And I am not trying to argue with anyone as I am not an expert.
I was told it was just A/C cars in 69, that used the Holley.
Those pics I gave where from a 1969 factory service manual, the only Holly it listed was a 440 and if I'm not mistaken only for a c-body.
Being from that time era and working for my uncle's Dodge dealership, my understanding was the 300-330 hp engine had the more restrictive a-body manifold and the 335 hp the other one. Have to ask Rhino if one of his 383 Darts came with the windage tray in 68-69. My m-code 440 has the tray and the a-body pan. Always thought that tray was worth more than 5 hp. Besides 330 was at 5000 and 335 was at 5200, that 200 could equal 5 hp. Just a numbers game
