You are correct, a high rod stroke ratio does offset some of the problems with flame propogation through the chamber. To be specific. It allows the use of less timing and a later spark initiation because the piston dwells at TDC longer but accellerates away faster.
Thats a little to technical for this site dude All I meant by the B18B comment was CTR pistons with a reshaped combustion chamber it will be interesting to see what this engine does whn its running.
