Holley carb identification

[x.system]

Anyone know how to identify what size a Holley carb is? I've got a duel quad hi rise setup I want to list but I don't know what size the carbs are.

just google the list number and Im sure you'll get a bunch of hits on the cfm

Normally-if i remember correctly the holly's are cast numbers on it..or was it a sticker,,i know its on the carb somewhere...

Post the numbers on the carb and I can tell you what it is.

[Jim mac]

the numbers or on the choke horn. like 3310-1 I think it will say list then the number.

Looks like the choke assemblies are missing from these carbs. The only other numbers I can find are 997 on the meetering block (if thats what it is) and 6R3359 on the top of the carb under the air cleaner.

The numbers will be right near the front air horn, see pic. Yours look to a 600 vacuum secondary, but the numbers will tell all.

I'd guess 600's.

[Jim mac]

could be 450 or 390 vacuum secondary, since its a small block set up. Jim

by the way what do you want for it? I think a tunnel rammed small block would look kinda cool in my camaro. Jim
