Great to hear some news on this project David
Have you calculated the dynamic compression ratio and what fuel will you be using ?
Depending on cam timing the DCR will be high with 12:1 CR and a longer stroke
Any ping problems ?
This should be conservatively a 390 to 400hp motor by my calcs with more available with software changes, 315 to 320 RWHP
It Will be good to get some knowledgable comments on this stroker conversion from someone dong it and not theory
Mid range torque should be awesome
