I do *think* so. I forget myself. I'm not so engrossed in the car world as I used to be. This is why I questioned the C-ratio. The 383's are finiky (sp?) much like the 318. They lack bottom end torque. A cam of the 292's size, which is a sizeable cam, can kill it dead quick. Installed wrong, just 2*& retarded will mess things up.
