I recently had a mechanical roller lifter failure. I have about 13k on the engine. It is a crate 514 from Ford. The tech line seemed surprised that I got that many miles out of it. They have suggested going to a milder cam, hydraulic lifters, different push rods, and lighter springs. I have already odered the parts to make the change. Woundering if anybody else has. They say I will probably loose about 30 to 40 hp which I guess is no big deal when you have 635hp.
