Help replacing the camshaft housing and cover

[eric.geiger]

So i found out some bad news on what i thought was my all original 72 coupe today. it turns out the engine is from a sedan. it saddens me very much but ill live. Now i need to make it right.
I've now learned the differences in the 2 parts by look. but as far as changing from the sedan to the coupe housing, how bad is it.
is this something that a more than average tech can accomplish or is it very difficult?
if someone can give me some insight into this it would be great. i don't want to go and buy a new hood then have it just get dented from the inside due to the height difference.
Lastly B&B was the one who pointed this out to me and they say its a late model sedan engine and would likely have the proper camshaft for the tach drive. if this proves true is there anything else besides the cam housing and cover needed to convert it back the way it should be?
Thanks in advance.
Also if anyone is in the seattle area or milwaukee area that knows about this task or has done one or could help let me know ill gladly pay for some help and supply the beer. i say both areas because the car will be in seattle until july then milwaukee after.

It is not the end of the world.  Remove the cam cover.  Rotate the crank until the scribe mark on one side of the cam sprocket aligns with the upper surface of the cam box.  The "T" mark on the crank pulley should be aligned with the indicator on the alternator cover.  If both marks are not aligned, rotate the engine until they are.  Remove the fan shroud bolts.  Remove the right and left cam bearings.  Tie a wire around the cam chain. Remove the rocker shaft and rocker arms, make sure you mark which ones cam out of which holes and the sequence in whickh the pieces cam out.  Lift the chain off the cam and remove the cam.  Now the cam box can be removed.  Hopefully you will have a cam box gasket, cam bearing gaskets and an intake manifold O-ring.  If you have a shop manual the job will be a snap.  Good Luck, Don Laughton

between reading the manual 2x today and your comments here it seems pretty straight forward.   what is the purpose of the wire wrapped on the cam chain?

Thw wire will make it easier to fish the chain out of the engine if it drops down.

There's more to consider besides the cam housing and the lid, left bearing housing & tach drive parts. What's the engine number? Also, if the housing has the casting bosses on it you could just lay the new lid on top and drill & tap the new holes. I showed this in one of my old newsletters. Some late sedans have the protrusions so you can save the extra labor & parts.

N600E-25XXXXX is the Z600 engine designation.  It denotes the narrower cam cover bolt pattern and not much more.  N600E-15XXXXX is the synchromesh or late N600 engine designation.  It also indicates that the engine should have the metal vacuum piston carburetor.Hope this helps, Don Laughton
