........... and engine builders top secret pencil.

Just a guess but does builder mark each lobe with lead from the pencil and then rotate cam to see where clearance "ends" and cam comes into contact with the tappet bucket ?

Or does he simply write down the clearances as he measures em ! - lol

Your guess is as good as mine.
I thought I would mention the pencil, before someone else did.
Other suggestions welcome.

Went to the engine builders to drop off some parts, took some pics while I was there.

Test fit of timing and oil pump chains.

Have u dyno'ed it or r u gonna run it in fitted to car ?

I have the 100 RON MBT spark map for this engines compression ratio and cam profile. So I will most probably fit the engine to the car. Tune the drivability and closed loop fueling on the road, and optimise the wide open throttle spark and fuel with a rolling road session.

Never seen cams so peaky ....

Well spotted.
These are not my cams, but cams with nominal base circle diameter used to calculate the valve bucket clearances.

Cheers

P.s I have just checked the engine to make sure the engine builder did not leave them in.

A few more pics.

I done a trail fit of all the parts that bolt on to the engine at the weekend.
Because all the previous engine installation work was done with a dummy (scrap) block and head.

My first mistake is that the alternator belt is touching the front cover (near the bolt in the center of the cover). I will have to change the 2.3 Ranger rear wheel drive one for a Mk1 2.3 Focus (North America) front wheel drive version. But before I can fit it I will have to get the engine mount bracket machined off.
