1968 Shelby GT350/500/500KR / Re: Cobra Jet cam
« on: March 30, 2023, 06:35:58 PM »
I've been using the Comp Cams 268H-10 grind in 427 and 428CJ's for years. It's a good choice. Smooth idle, lots of vacuum. A little more cam than the stocker but not much more.

The Ford Motor Company Pavillion at the Hemisfair in 1968 combined Ford, Lincoln, Mercury and Shelby products.

Anybody have any experience with either of these two cams: Comp 31-334-4 236@.05 528 lift 110 lobe separation or Isky 381358 236@.05 .512 lift 108 lobe separation?

I think either of these will be a lot of cam if you are limited to 289 CI. I took the same Comp Cams cam out of a '66 GT350 because the customer didn't like the lack of low end torque. I installed a Comp Cams 260H which he was happy with. It was more like 212 degrees at .050" and .498" lift. You can save yourself a lot of grief by adding cubes.

Replicas and Tribute / Re: New headlight switch

If you have flashing headlights the issue is too much current for the switch to handle. Fortunately, you can remove the halogen headlamps and plug in LED headlamps that are brighter and far less current. Problem solved.

1966 Shelby GT350/GT350H / Re: 66 Alternator Gauge Issue
« on: March 25, 2023, 05:55:10 PM »
OK, I made videos of my 1] current solid state voltage regulator, 2] a new solid state one and 3] an old-style reproduction of the original style [non-solid state] one. ALL exhibited the same jumping of the ammeter needle! So, my conclusion is the voltage regulator is not the cause. Hmmm. Now what???

Also, should the cover be glossy black or satin/flat black??? Thanks!



The voltage regulator is not in the ammeter circuit. The voltage regulator is connected to the field on the alternator so if that doesn't charge obviosly the ammeter is only going to show a discharge. But it's unlikely to be the issue.

Anything that you do to a voltage regulator on the instrument panels will have no effect.

More likely the instrument itself is bad.

Looks to me like the Ford Hemisfair display in San Antonio, TX. The built a special Rotunda for the fair. If it is the Hemisfair this is the only color photo I have seen of the display.

The best springs are the originals. They can be rebuilt and re - arched by a spring shop. My experience with the Eaton Detroit springs has been dreadful.

Not "if", all 1968 Shelbys, including 350s had the 31 splines 😉

If you say so - I've only seen the ones with a big block. Never owned or touched one with a 302.

Thanks Guys ! Its a 428. I just dont like the fit and frankly, the needle bearings seem pretty cheap.
Think I'm just gonna get it out and go with bronze solid one. Appreciate the input !!

+ 1 More reliable

Also 68 GT 350

Sure if those had 31 spline axles they would use them too. Never had one or worked on one so I don't know.

They look the same as the 31 spline axles used in 1968 to me. Typically found in GT500 / GT500KR / 428CJ Mustangs and GT-E Cougars. One of yours shows a date code of 8A. I suspect that's January 1968.

GT40 - Original/Mk V / Re: Aluminum Honeycomb
« on: March 19, 2023, 11:25:27 PM »
Honeycomb building panels have been used for building facades since the 1960's or possibly the late 1950's. HH Robertson made honeycomb panels that would fit into curtainwall and storefront framing systems.


Both the Gulfstream GI and the Lockheed Jetstar flew around 1958 for the first time. Both used honeycomb bonded floor panels. I believe aluminum honeycomb was first used for floor panels in the Boing 707 that first flew around 1955. If there was any earlier use of it I am unaware.

It's been used on production aircraft since around 1958. Maybe it's revolutionary for use in a car but bonded honeycomb sheet has been around forever.

My alternator gauge jumps around! Could that be the constant voltage regulator [new solid state design] also??? Next, where can you find a NOS or used one to try???



The alternator gage is not in the circuit of the CVR so it is not involved.
