The cam I need and want is a single bolt cam, all the gear drives ive found are all 3 bolt. Now all the 3 bolt cams seem to be requiring a higher compression or are really only effective around a higher RPM range and are kinda more of a race cam. So are there any single bolt gear drive sets out there? Just noticed I forgot to put that the motor is a 440.

 

i think edelbrock uses single bolt cams

 

Why do you want the gear drive set? There is nothing wrong with a good chain set. just my .02 worth.

 

Gear drives make that cool whine that sounds like a blower (at least the ones with the straight-cut gears). Personally I don't like a whiney engine, there are enough other whiners around.

 

What you are hearing is the wearing out process!
