If they are the early injectors (not the Multecs), this link may be helpful to you.
GM Fuel Injectors for Tuneport Engines 1985-1989.

The table for TPI engines is listed towards the bottom of the page. I can look up the part numbers for the LB9 and L98 Multecs also, if your need to match them to a found part number.

There should be a part number located on the injectors. I almost positive that the Multecs have a part number stamped on the body housing. Others should too.

350's came with 24lb injectors
Mcdamit, actually the stockers are 22# injectors.

You are correct. Not many people know that.
