The D/Dart came with the 2536771 intake. They used an in-house made 1/2" aluminum spacer/adapter for the 4160 Holley carb, list #3778. It was a 7?0 cfm carb with 1 11/16" throttle bores. Not sure of the exact cfm. The aluminum adapter had the same throttle bores as the carb, it had to, but I'm not sure of the intake. I didn't measure the intake on the car that I sold which would have been correct. On Ted's old race car, the 771 intake measures 1 9/16". The late Paul Ceasrine said it was a high flow intake and thought it was also bored to 1 11/16".

I think the LD4B with the Chrysler part number came out some time in the 70's.

Thought Galen's book was wrong with just the 318 only listing of the block.
