My understanding is that if all internal dimensions are correct for
either the 750 or 800 whichever is legal.........The carb is legal.

I have not seen them inspect the numbers for many years in teardown.

The Edelbrock come in either 750 (1901 /1902) and 800 (1903/04/05).
The only differences I recall is the linkage locations for GM or Mopar or
Ford within each size.

I have had the best success by far with the Edelbrock Carbs in Stock
and SuperStock.

George Thomson in Acton Ca. (Carb. Flow Engineering) has built my most successful carbs.
