I have heard of issues with the 2332 so far as excess heat, short lifespans, ......
Like Emilo said, you have to ask yourself how long you want the engine to last. When I built my engine, my intent was to not touch it for at least 100k miles. That was 8 years ago, now at 70k miles.
I picked 78x90.5 for a couple of reasons.
90.5 because I have heard of many instances of achieving 100k miles on these P&Cs. I have never heard of anyone building a 94 bore engine, then running it that long without a re-ring along the way. Lots of blowby is common at 30-50k miles.
78 stroke because with 82-84 strokes, you start to get more side loading due to the greater rod angle. Side loading on the piston contributes to cylinder wear and ring failure. With a 78 stroke, you reduce that problem. If you use a longer rod, you can get the same rod angle as I have, but with the longer stroke.
I use 40x35 valves. I prefer them for many reasons. One is that with proper porting, it is possible to make 160-170+ hp. Since my target hp is less than that, why use a bigger valve? Bigger valves need stiffer springs. Stiff springs lead to shorter cam/lifter life.
