Default cranks

I had a bolt on crankshaft in an Arnolt that I raced. The crankshaft bent spun a bearing and damaged the block. The block can be line bored and fitted with new bearings, but I am not a fan of the Bristol crank. The dampner weight on one end and flywheel on the other move stress to the middle. If the engine is used at 5k plus rpm, I think you can expect damage.
