I just put a Ford Racing 514 crate motor in my Superformance. I too had concerns like those raised in this thread. So far my experience is very limited, but I now believe that if I had it all to do over, I'd stay with the 514. The roller cam, in my opinion, is not too radical for the street. I'm idling about 850-900 and it runs great! I did swap out the stock Dominator single plane manifold for a dual plane Performer RPM. I was advised the Dominator would not operate very good for street use. And, I’m running a Holley 850cfm.

A couple of other notes... So far I have only used Blue Turbo, but the minimum recommended octane from Ford is 92, so later on I will try pump gas. Too, this motor has a compression ratio of 9.8:1. The 460 is 10.5:1, so the 514 should be a little more octane friendly than the 460.

As far as performance? Like I said, my experience is very limited, but I can say "Don't get in this car with a nervous foot"! The slightest quick movement on the accelerator will light up the tires. It's assume!!
