Bore and stroke for Thor engines?

[Phil Budne]

Didn’t want to hijack a recent post by Waunnaboat who had a question about his Thor opposed twin.

I’ve wondered about the bore and stroke of all the Thor engines; are they all the same as the early Mercury K1 etc (same as the Kx3 Kx4)??

I would not have minded at all.  Good question though.  They are probably all the same as the streamliner?  but I don’t know about the K1.  Maybe I will investigate the opposed twin when I hopefully get around to restoring it this summer.
