G'day,

My mate and I just bought a ski boat with a 308 in it. It has a Holley of some description fitted. Its 4bbl, square bore, vac secondaries, manual choke. It has a heap of numbers on the fuel inlet end, just above where it says "HOLLEY" they are 3,572,387;
3,343,520;
2,892,622. There is also a number on the opposite site to the choke mechanism, P-80.

At the top of the venturi, under the air cleaner seat is a number 7809.

Does anyone know how to identify these suckers. I have no idea how to tell what it is... ie, a 600 holley etc. At a guess, it would be something like a 600.

I have rochester in the shed I am thinking of sticking on in its place as the Holley is pretty difficult to keep running nicely - pretty thirsty too, but we are giving it a good workout.

Thanks for any help.

My search results show only one item, it would appear this is a rare Holley carby P/N 7809 is the carby part number, GM fitted this to early 80's model Silverado's with 350 Small blocks.
It is a 600 cfm square bore as indicated.
