hey I have a six pack that I buried out of the garage. all I know about it is that it has all the carbs and it's an edelbrock. But I don't know if it's for a 440 or 383. How do I tell?

 

There were no factory 383 sixpack manifolds. So if it's for a 383, it is aftermarket, will be aluminum, Edlebrock (maybe Weiand not sure) and will have a model molded in somewhere.

If it's cast iron, used on 70/ later cars, it HAS to be for an RB engine.

 

Look for a part number on it. It may be cast in on the bottom of it.
