I would not use synthetic grease like the redline product. Reason is the synchros will not be up to speed - the grease is too slippery and thus not competent for use. Really the OEM lubricant is best for a variety of reasons.

Correction:  Comet would share Fairlane application.  Cougar would share Mustang/Shelby.

This exhaust control valve had different applications using different designs other than for this topic.  Examples:
Galaxy, T-bird, even trucks, as well as Lincoln; same function, but different design for their application.

Pretty sure for 1967 model year all of them would share the same exhaust manifolds. The Comet / Fairlane / Mustang / Cougar all used the exact same manifolds in 1967 for the 390 and in the case of the Shelby, for the 428 as well. I do not believe the spacer was available in 1967 model year, being a C8 part number.

Quote from: Lincoln tech on April 16, 2024, 06:44:31 PMYou are talking about a "heat riser"?  Exhaust valve usually sits in cylinder head.

The description calls it an "Exhaust Control Valve".

The valve is listed in the Lincoln Mercury parts catalog as being applicable after January 4, 1968 P/N C6OZ-9A427-D. Curiously, the same chart lists the spacer for the 428PI application as C6AZ-9A427-B before 11/15/68. The spacer meanwhile is listed as P/N C8AZ-9A427-B (390, 428 exc P/C).

Quote from: Poor Ron on April 12, 2024, 07:29:06 PMI think the ID # are; C6OE-9430-A & C7OE-9431-A for unibody cars, such as our Shelbys.

True, the RH manifold was revised for 1967 since the one used in Fairlanes / Comets for 1966 will hit the floor pan because it is too long for a Mustang / Cougar application. The 1967 Fairlane / Comet got a revised H pipe so the new manifold would work.

The date codes are 6B3 and 6B2. Those dates are in February 1966 - Mustangs were not even getting FE engines then.

Glad he is OK! Glendale can be hit or miss...... lots of bad characters in So Cal.

I think the casting dates are too early for the car. Ideally the casting dates for the exhaust manifolds need to be around 6 - 8 weeks prior to the car being assembled.

The flapper was used on engine assemblies dated up through a date in February 1968 which means most of the GT500's would have them. The rest of the GT500's would have the spacer but those would be in the minority since the GT500KR replaced them.

I have had several of the reproduction steering wheels that had to be assembled properly to fix the horn not blowing. Two of them were shorted to ground which made the circuit breaker in the headlamp switch blow repeatedly until it burned out. One was open which was a little harder to troubleshoot but the hardware turned out to be the problem with that one too.

I believe that one of the hood hinges on my KR is defective and I want to replace it. can someone give me a paint color in rattle form, to make these look appropriate. I believe it is some kind of gray, but a specific maker and paint number would be great. Thanks Steve Meltzer.

The original finish on the hood hinges is phosphate and oil. I have not tried this but it is supposed to resemble the original finish.

Tom is a great guy. I watched his TV series back when it was on the Speed Channel (that was a long time ago!)
, then a couple years ago went to his place and spent half a day there. He is a legit car guy, the real deal. No doubt a great choice as speaker.

Very cool. AO Smith only did the sunroof installations briefly in the middle of production perhaps in April 1968. They had lots of trouble and lost money on the sunroofs, and afterwards they were done by American Sunroof as they had been before.

Dan, I'm sure you know this. I read years ago that all the blocks back in the 60's (specifically, and maybe earlier and/or later), were in fact seasoned blocks. Left out in a field and "seasoned" with the cold and hot of the seasons. I never heard much more about blocks being seasoned as we moved closer to the 5.0 era and beyond. That may have been why the small blocks specifically was so strong and bulletproof!!
Any elaboration is welcomed!

I think what you read is an urban legend that has no basis in fact. Ford cast blocks and then used them as need be. There was no set time period.
