Re: Camshaft end play

I had .093 end play on my cam I had to take the C clip spacer out because a dbl roller seats into thrust plate and a single tooth gear uses a flat gear on back. I ended up .002 and had to buy a .080 spacer, now I have .011 end play

The way to measure end play is with the thrust plate and timing gear installed using a dial indicator. The distributor gear creates a thrust on the cam that pushes it forward against the thrust plate when the engine is running.

Re: Camshaft end play

Ford cams are ground with "dual taper" on the lobes. This means half the lobes are pushing the cam forward and half are pushing it backwards to "neutralize" thrust load because it has a thrust plate unlike older GM V8s. Yes the same lobe taper that keeps lifters turning. ( unless it's a roller cam which have no lobe taper at all). A dial indicator as previously mentioned is the best way to measure end play. .005-.010 is considered acceptable.
