I have an old cam and new cam from megacycle cam. I noticed the new cam on the right has a smaller profile where ive got the screwdriver bit leaned on. Im still waiting for the cases to come back from machine shop before assembly but is this normal or should i be concerned? Bonus points for explaining any of the numbers on timing card
The numbers on the card tell when the cam will begin to open and finish closing your valves at degrees before or after top or bottom dead center of the piston. (ex: BTC = Before top center) There's more info there but you and I will have to do our homework to understand it better.
