All SB mopar edelbrock intakes were NHRA banned about 2 years ago. Prior to that For stock eliminator the 1965 273 for many years could use the edelbrock with the part number on it. There was minimal grumbling from the Chevy crowd. Then the LD340 was approved and there was more grumbling from the Chevy crowd. Because those 340 dusters are in the classes with all the small block 67-70 Camaro’s. Lots and lots of them camaros racing and they always cry like 2 year olds about the 340 mopars needing to add weight.
The BB edelbrock with factory part number CH4B and DP4B were never approved by NHRA in modern times.
Now the reason they were made with part numbers Is so they could be used for this when they came out, Like early 70’s, but I don’t know specific details on that.
