I also got a 275H Camshaft & Lifter Kit (Schnider Cam) I don't remmeber if the cam was included with the kit or if I ordered it separatly.  I had them install a direct port NOS kit too for an extra charge (never used it, no need for it :), I got Merlin BB heads from them too.

These parts were included in their 1993 TPI kit.  They might have additional/less parts in the kit now.

As you can see, many parts are from GM. So finding replacement parts is easy.  You can still use a scan tool.  IMPORTANT: Be sure to ask them to replace the MAP sensor with a 2-Bar MAP sensor if you are running any type of froced induction (a 3-Bar MAP sensor is available too)

NOTE: When installing the harness, you'll find that there are two wire looms going to the intake:

One has Injector connectors.

The other has IAC, TPS and other connectors.

BOTH looms will have the SAME shape connector for water temp. and intake air temp., be sure to connect it correctly.  This won't be a problem the first time you install the harness (all connectors are tagged), but if for any reason you must disconnect them, be sure to tag them.  I forgot, and had to use a scan tool to look up which sensor is getting a high reading.  You don't want the computer to have a reading of 180 F for the intake temp. and 80 F for the water temp do you.  :)
