went to back to the fifties to buy a new intake for my 77 grand prix with an olds 350 and bought an intake from a used part vendor. the intake only says OL4B on the top and Buddy Bar on the bottom. What does it all mean?

 

Check this out, explains some stuff, I know nothing.

OL4B is the Edelbrock designation for that manifold. Never heard of "Buddy Bar". Is this raised cast letters, depressed cast letters, or stamped or engraved letters? If the latter, someone just added them. If the former, I have no idea.

 

Buddy Bar is an aluminum casting foundry.

Thank you for all the info. The letters and raised on the manifold and good call on the alluminum casting foundry. Til next time......

 

Buddy Bar was a main source of castings back then.

 

That's awesome. Can't wait to get it on there. Thanks guys
