I would think piston height would effect exhaust port timingPiston height would effect the port timing , right?

Could you put the old piston back in it (crazy I know) and since you have the cylinder apart put a degree wheel on it to see if the timing is bad? Too kind of get a feel if that is part of the problem?Skirt characteristics would affect intake.
I hope you all are confused as I am about the subject.

Excellent stuff there, Mark. I for one appreciate it very much. The only anomaly is the .010" difference between the two at the top..., which essentially only affects the squish and nothing else if each rod provides the same piston stroke otherwise. As shown in the 6-10 IPL earlier, both scenarios can be applied to the same crank and cylinder in that particular model. There shouldn't be any reason they wouldn't interchange in other instances as well.
I've thought about it, but intend to wait until I get the one that the IPL says is supposed to be in it..., which looks like it's just gonna be a new version of the old one anyway and not a full skirt version like I've been theorizing it was supposed to have. What nags me now is whether it has the correct cylinder...
I truly appreciate everyone's input on this..., not to mention your patience with my continuous posting about it.
And a great looking project there, Vinny!
So is it just a simple case of swap in the rod that goes with that piston?
Did someone just put the whole crank/rod and piston in from another 7-10 parts saw?
