There are many people that claim to be experts on camshafts, some are and some are not.

you guys all seem to be very knowledgable so I thought I'd ask you.

My 406, I've been told by mark has a somewhat aggressive cam. I'm starting to think I may have been built to be a circle track engine or something, as it lacks power until higher rpms.

Wanting to change cams, but I don't know much about them honestly. I'm thinking maybe an RV type cam? It's in a 6500lb suburban, 3.73 gears and a th400, soon to be th700r4. So looking for really good low end torque, not worried about much over 3600.

What would your suggestions be? Thanks.
