Volvo Penta 3.0 GLP-J whats my carb cfm

[benclegg]

Hi
I asked Holley what the CFM should be either 500 or 300, Holley say 300, yet i've had a look on this forum and and found a mail that says the 3 litre is a Holley cfm 500?
Can someone confirm either way?

Well it's going to be a 2bbl Holley 2300 that comes in both 300 and 500 CFM's according to this site, http://www.jegs.com/p/Holley/Holley-2300-Marine-2-bbl-Carburetor/761848/10002/-1

But Volvo says the 3.0 GS is a 500, http://forums.iboats.com/filedata/fetch?id=7002744

Thanks Fun Times, Mine is the GLP model not the GS
So its all as confusing as I am confused?. The carb at the moment is a Demon with no ser numbers on it and it is knackered! In your expert opinion is it a 300 or 500?

Just found out that the GS is 150HP where as the GLP is 135 HP , so I guess the 300 CFM for mine? but I could do with some encouragement from experts?
