who can look-up some Q-jet part specs. I am looking for the data for both a 5.7LX and 350 Magnum. My service manual only covers newer engines and has only a couple of q-jets, but not for 5.7LX or 350Mag.

Looking for:

Primary Jet Size:
Primary Metering Rods size:
Secondary Metering Rods (2 letter designation):
Air Valve Wind-up (grams):

If there are multiple specs for those models, would appreciate all data, just provide the merc carb part number. Thanks in advance for taking the time and looking it up and typing it in.

Dave,

Thanks for the very quick response! I appreciate it. Those specs actually match some of the non-merc documents I found. I am not always trusting of those 3rd party manuals.

Does your manual specify the air-valve wind-up? On mine, its shown in a different table than the jet/rod specs.
