The 4800 model FI unit was used in '57 on Corvettes and passenger cars and in '58 on passenger cars, all in low HP, hydraulic lifter applications. The air cleaner in your picture is from a '57 passenger car. If it's original to that unit, then your FI unit came from a '57 passenger car.

The distributors are not '57 distributors but I can't make out the numbers to tell you what they are.

Jim is one of the most knowledgeable Rochester Fuel Injection people in the country. He can rebuild that unit correctly as well. There are a bunch of numbers on the distributor face plates that will tell us what units there were used on. Rochester Products made the FI units as well as carburetors . Many changes were made during the 1957-1965 production years. In 57 alone, they made four units. 4360, 4520, 4800 and 4960. In 57 they made a 905, 906 and 908 distributor. You could spend an hour learning about all the units and changes.

The system however is quite simple how it works and once dialed in on a good running motor will deliver high horsepower and good gas mileage. Todays ethanol gasoline is the worst enemy, and old 108 racing fuel works best in the operation of these 60 plus year old units.

Hello Jim and Jim, thank you both for the reply and lending me some of your knowledge. The distributor numbers are as follows, 1110914 serial 0 K 3, and 1110915 serial 7 H 29
Thank you for your help with this. It is greatly appreciated!

Your "914" distributor is suitably dated for a '61 Corvette and is for the 315HP solid lifter FI engine.

Your "915" distributor is suitably dated for a '58 Corvette and is for the hydraulic lifter engine. It is also a pretty rare distributor.
