Here goes nuthin…

 

Finally have some free time so I’m diving in deep and starting in on the O-520F core that has been sitting in the corner of the shop.

I will be using the 2000hr TBO  PPonk STC with Millennium cylinders (venturi seats).  Should give some nice additional HP!  The engine is finally apart and the parts are going out for inspection and overhaul.
