347 vs 331 Stroker?
The general "word of mouth", as I hear it...the 331 will rpm easier, but the 347 has more torque. Its more than the difference of 29 ci. vs. 45 ci. the stroke, crank shaft strength, and the rod angle/bore length ratio. But at the simplest level, the 347 has a bit more torque, due to its longer stroke. The 331 tends to live longer and run to higher rpm due to its shorter stroke and piston travel. As far as a street engine, especially if you intend to Blow or spray it sometime in the future...it's a wash. 'course, bigger is better, that's why you go for the stroker anyway, isn't it? Usually the cost is pretty much the same.
The pistons that have the full oil ring land are "usually" heavier, again affecting the RPM ability of the engine. I think even FMS has a 347, street kit on the books now, I'm not real sure, but I think they even have a short block? That's to say that longevity and oil burning, in the "short con rod" version of the 347 is not a problem.
