I would first off get a manifold vacuum gauge and do a compression test and then think about an Indigo prop or maybe a 12x6 two blade if you race.
My plans is the Indigo 3 blade for next spring. I'll do a compression test as it's been 3 years since the last one, when I picked up the engine. The vacuum gauge hovers around 15 at idle and I have to check what it says at "cruise". Last Aug when I first installed it, it would read zero at 'cruise"
