Holley Carburetor Question

I found someone on craigslist who has a Holley 2bbl for sale.
I'm hoping someone can tell me whether it will work ok for what I need.
I've got a 1963 chevy 230 going into a 1952 chevy coupe.
The engine is pretty much all stock. Except things that are irrelevant like dress-up.
The numbers on the carb are as follows:

DIJJ 9510 B
LIST 6317
121

From what I found on the internet, this is a marine carb. I found somewhere that said it's a model 2300 carb. 350cfm. Is this correct? I'm sure I'll need an adapter for it to fit my intake, but if I can get an adapter that fits will this carb work ok for my car (Assuming it's stock and no ones messed with jets and what not)?

Thank you so much for the help!

 

My old Holley book lists it as coming from a 1971 Ford 302 boat engine, no cfm rating given. Bolting it to an adapter on a stock 1 bbl. intake will have pretty much the same effect as shitting through a funnel---not efficient at all.

 

haha ok thanks!

What if I were to put it on the 305 in my truck. its got a 4 barrel intake and I have a 4 barrel to 2 barrel adapter, assuming the adapter will fit the carb.

 

Well Heathen thats not entirely true.I have a 54 235 with stock intake and exhaust manifolds and a mild cam.I put 350 cfm 2300 holley on it and it really woke up the engine,now you will have to jet it down (went 4 sizes down and next smaller squirter) tran dapt made adapter for my motor,not sure about your aplication.If this carb is more than 350 cfm then its too much,good luck.

 

If its a side inlet boat one ,Jets are 74 ,

 

If you put it on a 305 or any other 108 degree intake manafold, be sure to block off the center of the adapter, especially if it's got an egr passage. Otherwise it will be bog city until you richen things up a lot. But for a 305 a 500 cfm would probably work a bit better.
Good Luck!

 

Ok thanks for all the info!

 

most of the holley 2bbl's are 390 cfm, need to watch out for them, many are run in stock car restricted classes so they may have been modified heavily, check it over carefully

 

Your 230 needs 115 cubic inches of air per revolution. A 350 cfm carb will flow 604,800 cubic inches per minute. At 115 cubic inches per revolution, 604,800 cubic inches per minute will supply enough air to turn about 5260 rpm. This is assuming that the intake manifold will flow that much air.

 

I'll google around a bit then and see if i can find flow #s for the intake, though not sure I will find them. thanks!
