Magnum Roller Lifters

Morel makes solid roller lifters for small block Mopar. You would just do away with the spider and get custom push rods. The link below is to Hughes, but you may be able to get them from Bullet a little cheaper. Hughes just re-boxes them and makes more $$ on them. Maybe do some checking to see if you could run solid rollers on your existing cam. Some you can, some you can't.
