Todd, the head registers are an issue, but piston pin height is different between 71 stroke P&C and 66 stroke P&C. So you gotta look at both stroke and heads.
Yeah, that's why I mentioned "cylinders" and "stroke
alone won't give you the answer"...
I guess between all of us we covered the bases...

To answer your question brant, the motor does appear to have been rebuilt in the past. The current size of the pistons and cylinders is 96mm and the numbers on the cam says it replaces those found in a 2.0l... Also, Sorry! I should have meantioned the case is cracked and the motor is completely stripped... There is ready access to all parts. Attached are some pics of meantioned parts. Does this help anyone identify the stroke?
Thanks,
Brad
Those rods are for the 66mm crank. Disassembled, you can just measure the stroke directly... but also, the rod journals on a 66mm crank are 55mm, while they are 50mm on a 71mm crank.
Again, make sure that the cylinders are the correct ones for your heads, or you may be facing some additional machine work.
