Looks like you have an aluminum Edelbrock dual plane intake.
It should work okay if that's what you want to use.
If you want to buy a 1970 cast iron intake like factory , John supplied the casting number.
They also have date codes cast in them next to thermostat.
If you have a choice , you would want to select a date code that predates the car build by a short margin.
Your carb looks to be a side inlet Chevy.
Pontiac , Olds, Buick fuel line comes straight out front.
Not sure that fuel line arrangement will work with the RA pan.
but maybe it will
The factory correct numbered carbs are extra expensive now , and not required.
Here's a link to a very original / correct 70 Judge with some pictures , that just sold.
