Yup i'm just about to go look for it and see if i can find it but. if these numbers are correct. then HP is the LAST thing you should consider when i come to a cam system!!!!!!!!!
timing chain 633.5 hp. miliodon 636.3 hp, dual idler 634, jessel 633 hp.
average hp, chain 596.4, fixed gear 596.3, dual idler 596.3, jessel 594.2.
I can see how the belt drive "could" pick up hp at the track because its a lighter set up.
Gear Drive for the longevity (could ware out many motors and still have a good Gear Drive)
True Double Roller Timing Chain. Durable Long Lasting.
