Thanks for the perspectives, I am a novice, but I was just trying to figure out what i was reading.
the poster of this information stated that it would only increase low end torque at a cost of more friction and heat. which would create cooling problems.....but the 1/4 stroke difference between the 218 and 230 would only be 1/8 at TDC and 1/8 at BTC right? In measuring my engine there is about .1 inch between the block deck and the piston at its top height.
I was thinking about all of this because I have the gyromatic and need the 230 crank, but all I find around the graveyards here are 217s for rebuild. If I were to try this I would hand crank it to see where the piston meets at block height. it was just a thought. I was wondering why no one ever tried it.
