my son has a 1978 formula firebird wiyh a 403. it has a edelbrock intake and i am trying to find out which obe it is. the only #'s it has on it are 0L4B. i looked on edelbrocks site and cant find it anywhere any help would be great thanks  

Sounds like an older one. Edelbrock web site only has part #'s for current parts. But they do have a spot on their web site where you can ask them ?'s. I used it before and they were very helpful.  

OL4B...           hmm....... on a 403 olds...

i know that you ask for more info.....  

but...

OL 4 B    just might stand for OLds 4 Bbl....


here is a link to a chart of obsolete edelbrock intakes

dont be freightened by the mopar in the link..
