Never seen that one before!

Can't see that making any difference at all & depending how oil is fed to the bearing it could cause oil starvation.

Not saying it was not done to an FBE cause after they left Cosworth lots of engine tuners had a go at them trying to improve them but from Cosworth they had normal BOA heads with different cams + springs but the rest of the head was stock BOA.

I wundering about the oiling. I dont think someone will drill a hole into the outer cage of the bearing and looking at the pictures, it will close the oil hole as the bearing sits on it.

Like i said, i think its a cam bearing "repair". And why would someone use a ball bearing? a needle bearing would do the job beter.

These heads are special, the finish of the casting is different to normal, slight differences the more you look at them but still very close to a STD BOA head.

The bearings are the real difference, still don't think it would make much difference but I can confirm it's not a repair.

The story is the complete GD1 24V test engine was obvously revised, a guy involved in the project took this engine home for what ever reason, he had it running a good year or two before a 24V was ever fitted to a production Granada.

The guy moved on engine was forgot about & stood for some time, the guys cousin Chris took over ownership & rebuilt the engine including replacing the cam bearings.

However he replaced them with normal (non expandable bearings) which soon failed causing 6 valves to hit the pistons.

Engine is now in bits spread around the garage but complete.

This is what Steve (mak1cozzy) is now selling.

It needs 4 new correct spec bearings, 6 valves & rebuilding.

Also the oil spray fitting that is said to be in the garage somewhere?

Are the cams, except from the bearings, different to?
