Not true at all. Ford Racing Performance Parts has a very "conservative rating strategy". See the 10 dyno tests from magazine articles and builders on the 392 I posted: Ford Crate 392 Stroker GT40 Heads Actual HP Documented in Magazine Articles Ford tends to underrate by 15hp - 30hp across the board on their crate motors. and it has been well documented.

I think some of the brand name guys like Roush and Keith Craft tend to be accurated with a proper tune as well. So many things affect the numbers, jetting, choke blade, temp., altitude, oil choice etc... So many guys spend $20 grand on an engine, but won't drop a couple hundred on a good dyno tune.

I have a Keith Craft 408 street crate motor being built for my SPF. I’m sure I’ll do a follow-on dyno run at my buddy's shop later this year. I’ll post the numbers.
