It's a 4160, and a 600cfm.

600CFM, 62 primary jets, 134-39 secondary plate, 12.5 power valve, .031" squirter, black secondary spring, 1 1/4" primary venturi diameter, 1 5/16" secondary diameter, 1 9/16" primary and secondary bore.

thanks guys... one more question, how are the secondary metering plates sized? say in this case, the 134-39 metering plate would be equivalent to what size jet if a proper secondary metering block was used?

That m/plate has a .073" hole which equates to a 70 jet.

first off, a good rebuild kit would solve most of your problems, probably has a blown power valve also (part of a rebuild kit). next, a new vacuum secondary diaphram and spring kit would probably cure the boggs/stumbles.
