The L32 injectors will work fine if you want to wire in the proper injector wiring connectors for them. If you don't want to wire in the different connectors, you can use L67 injectors. The L67 injectors will work fine in the L32 returnless fuel rail.

For fuel pump, if you are keeping the engine stock or just doing a few light mods (nothing that pushes the engine power over 300hp), then you can use the Delco EP-381 fuel pump.

If you use the returnless L32 fuel rail, you must mount an external fuel pressure regulator somewhere and I recommend you use a vacuum+boost referenced regulator. I usually just cut the stock regulator off an L67 fuel rail and mount it down by the fuel filter and connect it to the system as seen here:

I forgot to mention that the fittings used in the above picture were all -6 AN size. You will need a 37 deg AN flaring tool if you are going to use AN fittings. Standard flaring tools only do 45 deg flares and those aren't really compatible with AN fittings. Summit Racing or Jeg's should have everything you need including the flaring tool for the steel lines.

Did you mean 60 lb/hr injectors that have the same electrical connectors as the L32 stock injectors? (Stock L32 injectors flow about the same fuel as L67 injectors) Not quite sure what you are asking.

Any injector that will fit in an L32 will also work in the L67 rail. Any injector that will fit in an L67 will also work in the L32 rail.
