Always when an engine model was available in 1971 and 1972, there was a power drop - apparently due to the dyno methode - but was that always the case?
Exactly how much of a difference would it make on let's say a 1966 275hp 327? Or a 1970 454 LS5 (390hp)?

My original question on Chevytalk was to get the list specs changes of the LS3 402 between 1970-1972 when this idea came up. Just to see the full SAE specs difference in comparison would be great!

Thanks, I saw later when I updated my account... At least it doesn't say "Toyota", but it's not that far off...
