Mecum Red GTE Engine Rebuild

The GT-E was only available for a few brief months in 1968. Total production would not have kept the assembly line busy for more than a half day. If you know anything about a GT-E, it is important, and this is the place to share it. The GT-E registry is maintained by Jim Pinkerton.

No tensioner bracket. The upper bracket is unique as the adjuster slot is twisted to horizontal and curves over the top of the pump. I would make the smog system non functional. Remove the vanes from the pump and plug the ends of the tubes in the heads and vacuum hose. It looks functional but won’t rob power and the tubes won’t burn at the heads.
I am very familiar with the tuning of the smog era high performance Fords. The thermactor system in itself does nothing more than inject fresh air into the exhaust ports of the engine which dilutes the exhaust charge coming out of the engine. The real power robber in this era is the distributor centrifugal advance and the dual port vacuum advance. The dual port vacuum advance was designed to retard the timing during different engine loads. This was done by allowing vacuum at the port closest to the distributor cap that sucked the vacuum advance backwards retarding the engine. The Christmas tree sensor in the thermostat housing was designed to allow full advance when cold and as the car warms up to allow the retarding of the engine timing.

I have recurved the distributors of these era cars and disabled the port on the vacuum advance closest to the distributor cap to basically remove the retarding of the engine under loads. All looks the same but the power is restored.

The auto industry found out that an by retarding the engine more completely burned the gas charge in the cylinder. One would think that this would make more power, but it did not. And gas mileage suffered. To me all of this was stupid as more gas was burned up to supposedly make less emissions. And the thermactor system was only to fool the exhaust measuring devices by diluting the exhaust gas.

The 427 GT-E doesn't use dual port vacuum advance. It uses a single vacuum advance.

I actually knew that Royce. At the same time I was trying to dispel the myth on the Thermactor system. Maybe I should have moved this to a different thread on the site. I already have one private message from a 302 2v owner who wants help with his dizzy. Keep in mind that many GTE owners have multiple Cougars that are not GTE's.

The 428CJ GT-E did use dual advance if the car had a C80F 12127-D distributor. Oddly enough this distributor was used on all manual 428CJ's but only some automatic CJ's.

Mock up of the front of the motor and the smog system is complete. Correct white fan smog pump and huge thanks the West Coast Classic Cougars for most of all the parts. Still need a smog pump tensioner bracket if you have one! Plan to land the motor on Tuesday!

Looks pretty good. A couple things could be better:
1. Power brake booster line is the '69 type. In '68 that line is simpler, straighter.
2. Fuel pump looks like a low performance AC type
3. Oil pressure sending unit looks like maybe an electric aftermarket under dash gage?

I wonder about the booster line. Most of the stuff on this engine were original to the engine. All of the PCV fittings were present and intact.

Oil pressure gauge is my liquid filled "start up" gauge. It will be removed after start up.

That's the one that was used on Fairlane / Comet in 68 - 69 and Mustang / Cougar in 69 / 70.

Forgot to add, the alternator fan should be zinc dichromate, not black.
