Hilborn,but can you tell me what this one is for

First of all I know it is a hilborn unit.It has s part numer that is 303-C 8B(8?)not for sure on the last letter.I have had it for a while and never had any luck finding out what it may be for.I will try to post a couple of pics.

 

Any help would be appreciated.

 

Oldsmobile. Early rocket engines.

 

1949-1962? OHV8 Olds Rocket Engines, the HAMB rocket experts will chime in and give you an exact year of interchanges... I have the same unit and was told it fit the earlier motors, but I matched it up to a 394 intake gasket and it fit perfect.

Thats a very sought after piece you have there, you should build a car around it.
