Volvo 3.0 GSP-C carb jets

[mcallan1972]

Hello all.

Would anybody have the carb specs on 2003 volvo 3.0 GSP-C with holley carb 80316-3? The main jets were so dirty I didn't realize that the two jets were different and now can't find any info on what one goes in port side and what goes in starboard side of mixing block and dealer is not being helpful. From what I have found is that when the two are different it seems the smaller is on the starboard side.

Thank you to all in advance.

Been there done that and found nothing. Even reached out Holley, no reply.

Your carb is a 500cfm model

In my VP Service manual I did find one 500cfm Holley 2300 that used two different Main jets(all the other carbs used the same jetting on both sides) but it only lists the VP Part#

I did see this on this forum possibly your posting from years ago. I also have 2.5 power valve but 67 and 68 jets. My carb VP part number is 3857981. I may have to put the smaller jet in the primary starboard side and start from there. This carb for sure has never been apart before, unless they sent back to volvo to have it re-painted red. Thank you for all your help folks.
