The Eagle 5.7L Hemi, went into production in 2009, using the same heads, intake, etc at 395hp, with amazingly few year to year changes to 2022. I can't think of any other production engine that has remained that many years without perpetual modifications since the Model T. Just look at all the changes to the LS engines had in the last 14 model years, or a Dodge 360 from 1985 to 1999.
While engines like the Chevy SB, VW beetle, Buick 3.8, and Ford Windsor stayed in production for 40 years, there were significant changes every 2 to 5 years with different heads, cams induction, or accessory designs, etc. The 395hp Hemi has been using the same part numbers for an impressively long time!
