Default Re: Curious about the engine, :question:

Map, maybe Im missing something? The rod in the link is a ZAF80, the missing rod in the vid right? Its a 38mm long rod(114mm) to be used with the high pin piston. The FM80 a 38mm stroke crank with a long rod. Both rod/crank combos make a GT5 and I betting the piston comes to the top of the jug.
The ZAE50 is a 38mm short rod(110mm) and will come up about .062 low in the jug, hence the 1/2 breed. I have a Flying Horse that has the 40mm crank with the ZL rod. That's a standard 40mm engine. Daxes used to be that way, but the Dax I have now is 38mm, making another 1/2 breed in a standard jug. So there have to be different jugs out there. Or the long rod 38mm GT5 will pop out of the jug.
