Howdy,

Does anyone have know the diameter the journals ought to be for the cams in the 400? I bought an OSHC quite a while back that I intend to put on the intake side and run a stock exhaust cam.

It's a little scored so I was debating bringing it to work and having it tossed in a lathe to just barely skim it to take down and high spots or burrs. I got it for so cheap that if you think this is a really bad idea to run be honest, I don't have much invested in the idea of running this cam. If it ought to be okay then sweet, if not oh well.

Oh, and as a foot note I'd definitely Plasti gauge it, just not looking to waste one of our machinist's time if it's already on the small side of things.

Here's a pic of the offending cam.

Ope, found the diameter spec in the service manual lol. This cam is toast, gonna make a coat hook for the garage from it now I guess.

Yeah it was ovaled a bit too, was worth a shot anyway.

Why did hotcams even change the spec on the new style? Boggles my mind why they didn't just add a decomp for the exhaust side and call it a day. If nothing else why not re-release them since they are sought after.
