wipe cam lobe?

[pitoturbo]

what's the symtoms of a bad cam or a wipe lobe? would the engine misfire or valvetrain noise? who make a good roller cam for the street w/o any mod to the block or using roller rockers for irons heads? thanks pete

In my experience, a wiped lobe will cause the engine to run rough and you'll see the needle bounce on a vacuum gauge. It's easy to verify by simply pulling the valve covers and watching the rocker arms.

The Comp Cams roller cam setup is a 'drop-in' with no block mods or roller rockers required.
