That's right Paul, I should have said it differently; turn the crank clockwise, if the the next cylinder to come to TDC compression isn't number 8, then it's a counter rotater. Confirm by going back to number 1 TDC compression, then trun crank counter clockwise 90 degrees, next cylinder to come to TDC compression should be number 2.
This isn't for just Mopar by the way, LH and RH firing orders for the other gas enignes commonly used is the same.

The reason I brought up looking at the valves , take a normal rotating engine if you rotate the engine backwards you will get compression on #2 just like a reverse rotation engine , Why you may ask . Simple the exhaust valve became the intake allowing air to the engine . that can throw you off . ever try to get one running that someone put the wrong starter on . I have more then once .
I know we are beating a dead horse here but this one of the most confusing things about marine engines and many costly mistake have happen .
Larry , Just a thought do you happen to have a photo of the spacer used on the distributor ? Also of the cam gears and distributor drive gear . that could real useful to some one at a later time

I will take a photo of the distributor bases of both engines which will show the spacer on "Chrysler 318s " and try to take a pic down the distributor hole at the camshaft gear to show the difference normal vs rev rotation. I am not going to pull my distributors to get pic of distributor gear. I have one of each in long block on pallets presently without distributor in them, not sure if photo will work well down the distributor bore hole but will try.
And your are correct the sure way to tell is be sure the valves are closed, ergo compression, and that is true on any 4 cycle engine

Speaking about #1 cylinder on a Chrysler 318, here's some mind numbing reading !!!!!!

I don't see that. I see two boaters pointing different things that both know and coming to agreement and giving me the answer I needed on this 318 long-block I'm about to sell and not being a mopar or ford marine guy and dealing with GM's I just learned some good info from it...as in most cases if one looks at it as a problem it will be...in their eyes
