The fliptop comp cobra aka "the turd" had a aluminum block 390 that Ken miles drove. It was also rumored it was installed in CSX2196 and CSX3002 for a short time. Block was cast like a sideoiler with thick steel sleeves. One of the rarest blocks made to date I've heard. The last I heard it surfaced back in 01 and was sold. not sure of the whereabouts today.

It's how many bolt holes exist in the exhast port flange. Eight bolt holes is the regular passenger car pattern. Fourteen bolt holes are for the unibody (Mustang/Fairlane) cars. C8AE-H heads were drilled depending on what car they were going on in the final assembly.

If your heads have the eight bolt holes, then you can not fit the correct factory manifolds to the car unless you pull the heads and drill and tap the exhast flange for these manifolds.

If you do have the 14-bolt flange, then you just need to get the correct unibody manifolds.

The first engine was a 390 from a 2 owner 64 Thunderbird with 62000 miles. It was latter destroyed in a garage fire. Thats when I got it. It had never had any internal work done. The second was a 390 from a wrecked 68 Galaxie 500 with 72000 Miles. Because of the mileage, this engine got a precautionary new timing set before it was installed. It latter had the heads redone. Both engines were run in the same 63 F-100 p/u with a truck 4 spd. Both engines ran a little rough right before they quit. On the 68, I pulled away from a light in second gear, shifted to third and it  backfired about three times hard, made a lot of bad sounds under the hood and quit. It would not restart.  The 64 did about the same but I was going about 45mph and it popped 2 or 3 times and quit. Latter, I tore both down and they had jumped time, had broken cam thrust plates and bent valves. The plates had broken in the middle and were nearly identical breaks. I've been wrenching most of my life and I've never seen this before and certainly not twice. But thats kinda how my luck goes. LOL I'd tend to blame faulty engine work at some point, but I knew the history on the 64 and it had never been apart.

Here are the details. The first engine was a 390 from a 2 owner 64 Thunderbird with 62000 miles. It was latter destroyed in a garage fire. Thats when I got it. It had never had any internal work done. The second was a 390 from a wrecked 68 Galaxie 500 with 72000 Miles. Because of the mileage, this engine got a precautionary new timing set before it was installed. It latter had the heads redone. Both engines were run in the same 63 F-100 p/u with a truck 4 spd. Both engines ran a little rough right before they quit. On the 68, I pulled away from a light in second gear, shifted to third and it backfired about three times hard, made a lot of bad sounds under the hood and quit. It would not restart. The 64 did about the same but I was going about 45mph and it popped 2 or 3 times and quit. Latter, I tore both down and they had jumped time, had broken cam thrust plates and bent valves. The plates had broken in the middle and were nearly identical breaks. I've been wrenching most of my life and I've never seen this before and certainly not twice. But thats kinda how my luck goes.

Something that would have enough force to propel the cam in that fashion...well, I guess if, and this is a big if, you had a valvetrain collision that cause the lifters to propel the cam forward due to the taper of the lobe...naw, not even that seems possible.

Did you use the correct cam gear? It's obvious you replaced it in one engine, but not the other. There are two cam gears.

Did you install the thrust plate in the correct orientation?

Really, the only plausable thing I can think of is that the plate came loose, the cam walked forward, and the plate was ultimately destroyed as a consequence of everything else being destroyed.

This cam walking is pure theory. Once the lifters come off the cam, everthing jambs and who knows what forces are in play in those circumstances.

That it happened to you twice is really wierd.

Hope someone else has something better than I presented. I would regard it as the mystery of our time.

 Very doubtful on the distributor doing this. -- Gerry Proctor, 02/09/2006
If something causes the oil pump to sieze, the driveshaft will either break or the distributor rollpin will shear. Those are your two weak links there. For the distributor to drive the cam out the thrust plate, the distributor would have to be turning the cam, which, of couse, doesn't work that way. And even if the driveshaft and rollpin didn't fail, the distributor would turn in the bore and kill the engine.

I don't know that you'll ever get to the cause of the failure but some things can be ruled out as causes.

I really think that the thrust plate failure is a consequence of another failure. In other words, it got taken out in the carnage. There's just nothing forceful enough that can drive the cam forward and break the plate.

Thanks everyone for the help. It seems like there is no clear reason why this happened. I'm out of ideas. I either missed something during teardown or I've forgotten something that would have helped solve this. It has been several years since this occured.
I re-thought the project and I'm leaning toward a physicaly smaller engine. Maybe a Y-Block or even a Flathead. Its going to be a light car and I really don't need all the torque an FE produces. A smaller package will be easier to fit too. Thanks guys.
