Default A piece of art - 66 WV Unit

Most every Muscle Car from the mid 60s and up (that came with Smog equipment) was looked at as a horse power robbing maze under the hood.

These Smog components were commonly removed and tossed in the garbage.

Today, a complete factory unit is a rare site.

The 66 Tri-Power pictured below with all it’s plumbing would have bolted to the top of a WV coded engine of this year.

Complete with full steel fuel lines, secondary Smog air filter and 3 “flame arrester” screens made up this complex unit.

Priceless piece of art.

Chris.

I was not aware that Pontiac used STEEL Fuel Lines on the Tri-Power Carbs in any production application, (even California), learn something new every day.

I thought all the fuel lines to the carbs were always brass fittings and aluminum lines.

I've always said that the vacuum secondaries were an "elegant' design solution for the day. Given my troubles setting mine up, it is challenging my view but not yet soured me on it.

Same can be said for the '66 Cal smog setup (even the Jan '64 thru '65 Tripower Calif closed crankcase vent system adds interest for me).

I love seeing these unusual details and agree, early smog equipment was not all that reliable and often blamed for poor driveability (often with good reason) so commonly removed (or at least, defeated) to fix engine performance complaints.

Seeing the rare '66 Calif system is art worthy for sure.

Default Separate Air Cleaner for the 3x2

The unique “one year only” separate air cleaner for the 66 3x2 Smog GTO.

The filter (A224C) inside the air cleaner is a simple sandwich design. A thick oiled foam envelope wrapped around a heavy perforated steel support which slides between the in and out tubes.

You can see the dirty inside half with cap removed. Another air cleaner shows this steel support without the foam.

This “oiled foam filter” was of the same design as the OEM filters used for all the carburetors when new.

Default WV parts

Chris,

Love your attention to detail, MANY very hard to find parts there! Here's an intact and working system as well as a portion of a "Recall" letter from Pontiac. The original owner believes the "backfire" screens were added when the car was returned for this work. This car too has original steel fuel lines.
