Does a Ford 8N engine have camshaft bearings? If not, does the wear on the camshaft journals in the block ever reach the point of rendering the block unuseable?

The Ford 4.6 V8 engines have no cam bushings. Each head carries a camshaft and it is simply machined to fit the bore of the head. Each bearing has a cap similar to a main bearing cap. (Don't mix them up)

Not as original eguipment and no - the block doesn't usually wear significantly. If in doubt just mic the bores.

Back in "the day" it was common for SCCA folks campaigning TR3/4's and such in club racing events to install cam bearings. The 4 cylinder TR engine was little more than a Ferguson tractor motor with a pair of SU carbs strapped on and it too ran the cam in the block without bearings. I think it cost me about $90 back then to have a block bored and cam bearings installed as shown in Dan's picture. Not sure it accomplished much other than making me feel good.

If the "N"'s camshaft running without bushings in the block surprises you, you'd probably be DOUBLY surprised to know MANY "modern" overhead cam engines run the cam in unbushed supports that are part of the aluminum cylinder head.

And some of those little "ricers" run pretty darned fast, compared to an "N"!

I asked these same questions to a very experienced friend of mine a year or so back.

From what I understood...

He says you don't really realize how much slower the cam in these engines turns as compaired to most newer engines, and that is why they didn't put cam bearings in them.

He says it is possible for them to wear to the point of having a problem, and loosing oil pressure, but that in all of his experience he has never seen one have that problem.
