I Want It, But How Much Will It Cost?

Then aside from all the rpm-range-b-s, what you're saying is you're comparing a 392/408/427 cubic inch big-4-barrel-carb Windsor stroker to a pump-gas sipping, emissions-compliant, 100K-mile-warranted 330 cubic inch motor, albeit, with a blower (that could, in the privacy of someone's garage, have a smaller pulley substituted for the factory one).

OK.

Want to compare a 514 to a 427 now? Your choice: 427FE or 427 Windsor against the 514. Let's hear about how a 514 can match the performance of a 427...

choose to believe whatever you would like sizzler, the RPM ranges and power figures are accurate, and were the result of an ongoing engine development program. Yes a 408 or 392 or 418 stroker is a "351W" and I dare you to be able to tell the difference between them without removing the oil pan or cylinder head, because you can't, they have the same weight and external dimensions. And yes, those HP and torque values were on pump gas, CA pump gas at that, where you can't get better than 91 octane. I have never heard of a 100K warrantee on a crate motor, and since this discussion was based around a cobra enthusiast putting said motor into their cobra, crate motor is a fair assumption. Emissions compliancy doesn't mean a hell of a hoot, the original poster was trying to decide between the blower motor and an FE, I don't see too many cobras with FE's that are smog compliant. There is nothing revolutionary or even exciting about a 500 hp blown small block motor, maybe there will be something exciting after the aftermarket plays with the new design, but not yet.
