Has anyone ever use the Howard's Rattler camshaft or heard anything about them I know that Comp cams thumpr just gives you the sound and the Howard is supposed to give you sound and performance? THANKS
Howards cams probably rattle when the hyd flat tappet lifters fail like they have for me. One failed right out of the box and the rest have been dying gradually one at a time.

I wouldn't say no performance gain but it doesn't match the sound. It's suitable to people who want a performance sounding cam. Speaking of comps thumpr flate tappet cams. I'm sure the roller thumpr are similar.
