Cam Gear Drive?
do you think you could make a Mopar gear drive using a Ford 300 gear set with an extra crank gear for a 3 gear chain? You'd have to turn the IDs to fit the Mopar cam and crank and then install a bearing and maybe a torrington bearing set with some sort of retention plate to affix idler to block as well as an offset mechanism to set clearance. I never knew the 300 inline motor had a gear drive.
