Porsche Grob engine

[touringmandan]

Is anyone familiar with the Porsche Grob 2500 power glider engine? I have picked up most of one, and would like to build it for a 914 wide body project. Anyone know anything about the cam specs? I assume it's a low rpm torquer, as that suits prop drive. I only have 1 piston/cyl. set. The cyl. is kind of cool- 100mm alloy with no liner. Alusil/Nikasil?
I only have one cylinder head- looks like a ported 914 2.0 head. Any/all info regarding this setup would be appreciated. I would also be willing to sell/trade all of the aircraft specific parts if you happen to need them.
Thanks, Dan 704-993-8335 cell
