In my manual it states nothing about putting the cam / chain back on and where it should sit. How do I know what position the cam on top should be when it is at TDC for 1-4 or 2-3 ?? I the only mark on the cam is a "T" and that is facing up when it is at TDC for 2-3. Anyone have any ideas ? (Johnny what kind of beer do you like ? ;)

i'm not trying to mess with you. There is a relationship between cam postion/firing position of probably no 1 cyl. at TDC. It's probably in the manual, just difficult to interpret. Haynes? Clymer?

Been there. Still there, actually, Noone here has been able to tell me on the 350 whether the cam point pin should be at 12 o clock or 6 o clock . . ..

Jesus. If I dont see the sun soon . . . . . I cant sleep. Race weekend coming up. Gotta buy a tent. Owe people money. Gas is expensive.

I think we are getting it worked out.

The engine is basically two 175's glued together. Two of the four pistons go up and down at the same time...but fire alternately just like a 175. He found the timing marks but they are done in such a way that it doesn't appear to matter if the cam is 180 out...hard to explain.

Igniton can be 180 out... but the cam? There should be and L on the cam somewhere. Your manual should say whether or not it needs to be facing up or somewhere else. It has to be in conjuction with the LT (from what I remember) on the stator/rotor thingy.

It was kinda weird...the sprocket had a line through the center line of the cam all the way from one side of the sprocket to the other. You line that parallel with the top of the head with the crank at TDC. Of course you could rotate the cam 180 degrees and it would still line up....so it specified that the cam lobes for #1 cylinder should be pointing down...that tells you which "180" is the right 180.

Evidently JD is not the first person to be stumped by this on the SOHC fours...I saw numerous mentions of it on the SOHC forums when I did a search.
