Hello everyone. I haven't posted here in a long, long time. I am running a 350 Holley on an OZ 250 2V head with a 200 block. I am curious as to what size of jets people are running in similar setup. I am thinking mine are too big. I downsized from the factory jets but can't remember what I put in it. Any suggestions on what size people are running would be greatly appreciated. Thanks.
 
I believe the 59 or 60 jet will get you in the ballpark.
You really need to get an AF ratio either on the dyno or with a quality wideband tester.
Cruise 14.5-14.7, WOT 12.8-13.1.
