I installed the Opti, WP, headers, misc brackets, plug wires and various sensors. Getting close to be able to stuff into the Impala.
What make are those plug wires? Unless it's an optical illusion, those wires look really huge from this perspective.

Two more questions:

1. In the last picture there is a piece of tubing going vertical right after the LH spark plug boots; what is it, a crankcase ventilation?
2. What's the pipe fitting tubing that's coming off the #1 cylinder header tube?

Thx!

that tube is for the air pump (emission).

The fittings on the headers are for the check valves that are part of the air pump system

Those wires are big wires. I purchased the custom plug wires from Rustic racing many years ago. I am not sure about the physical size of the inner plug wire, but including the outer wrap, the wires are 13mm.

More photos as the engine and transmission are now in the Impala.

Why keep the air pump? They do sniff tests in Texas?

I believe they do in the Dallas and Houston areas.

Yes, unfortunately I have 1995 that has to pass the visual and pipe sniff test for a few more years. The setup that was specified for me was chosen to be able to pass the sniff test in the area where I live (DFW).

Exactly what I was thinking. The removal of the Airpump won't affect your emissions but will fail the visual obviously. But you could still "disable" it as outlined in the TSB.

================================================== =============


'95 Caprice SS conversion - Bonny Buckets - 96 Column, Shifter and Console - 3.73 Gear and Herter tune - Z/28 Cluster - Blazer OH Console - Green/Pink bushings - Chromed Impala Wheels - Eibach Springs and Bilstein Shocks - Corvette Engine Dress - the list goes on and still more to do...it never ends.

Well if Madamorr emission testing is like here in Calif. you need to have air pump installed to pass visual.

It does not have to work "if" you have the "disable" sticker issued by GM

GM part # 12569123

In looking at the TSB the service labor only has PCM re-flash for 96 (OBD2). For 95 I believe you can just pull the relay without throwing the CEL on...which "disables" the air pump

GM didn't want to pay the labor to "remove" the pump and cap off the exhaust manifolds, just pull a relay and flash a PCM for 96 cars. It is the specific language in the TSB, and sticker, that says "disable"...not "remove"

The TSB is for:

95-96 RM, Cad Fleetwood, Caprice & Impala with 4.3 or 5.7 engines

What do you mean it won't affect your emissions? Isn't that it's sole purpose?
