Reading all the posts over time I concluded 1) gear drives are best for medium race RPM engines with really stout cams say up to 7500 RPM 2) At really high RPM a belt drive is better... the gear drives can create/transmit their own harmonics




i've posted this before take it for what it's worth

not saying belt drives aren't good (i have one as well as a milodon) but i wouldn't consider this a "medimum RPM" engine. i'm pretty sure these guys had some insight into race engines and they were OK with a gear drive.
