Does anyone know what we're looking at here? I'd swear that the cam lobes are press/shrink-fit on the shaft and have splines at the I.D. That better be a really nice press fit if it is, or those are going to eventually loosen up with enough thermal cycling and stress.

Can any Ford experts shed any light on this? I'm assuming there are some benefits for modular design and manufacturing cost, but the logistics of the whole concept are slightly bending my brain. I can't even imagine what the stress concentration looks like around those splines on both the lobes and the shaft.

thats a very good find. I wonder if they are fused together.

 

That chamfer (or lack thereof) caught my eye when I was flipping through the gallery.

I need to get one of those engines. This looks like one of the most interesting production engines to ever come out of this country. If I ever build a street rod, this is probably going at the top of the list. Can't be very expensive either, if it's going in a high-production Mustang..

 

certainly doesn't look lathed/forged out of a single piece. That would, I think, ultimately lead to failure at some point.
