If I have about $100k to replace my 337, which should I buy and why?

The paper referenced above by Roger, written 15 years ago, calls the Continental IO-360-series engine "problem-prone". Is that still the case? Or did the VAR crank and other ADs resolve the weaknesses? I am under the impression that it is the latter, but I'm not certain.

I have flown both the p and non-P TSIO 360's. To me the biggest difference is the P-model has a red line of 37", thus the extra 15 HP. You really must run the p-model 360's much harder. We all know what happens when you run a piston engine harder.
