what direction does piston pin bolt face twd cam or away from cam

Don't think it really matters tecnically - especially on a std 20 hp car but most restorers puts the bolt away from cam so the thrust force doesn't come so close to the split. The pistons would then have their splits also facing away from the cam, so the main side thrust goes on the unsplit side - piston direction might make more difference?

Here's one of several earlier threads: http://www.mtfca.com/discus/messages/331880/334568.html?1357965611

Most of the ones I've seen have the wrist pin bolt facing the cam side. It probably doesn't really matter, but that seems to be the norm. The split side of the piston goes away from the cam, as Roger noted.

^ wow I'm glad I just read about the new wrist pin bolts breaking..., now how do I tell if I have originals or reproductions?

Fitting the rod backwards runs the risk of breaking the bolt and/or the rod. Fit them as Ford instructed, and by design for max strength, bolt to the cam.

Thanks for that, Frank. I know that's the way I've usually seen them, and the way most folks I know do them. I'll keep doing it the way Henry told us to. :-)

Great info, I have always put the dippers and the cam bolt facing the cam,how I was taught. Pray for San Bernardino.

That would be Rod Bolt faces cam.
