14th year of production for Eagle 5.7L, a record?

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!

It certainly has been around for a while, what's really amazing is that it is still competative in terms of power and fuel economy of much newer engines. Of coarse the 8 speed transmission helped with that when it come out in 2013.

Nissan's VQ35DE and maybe the QR25DE have been around for a while now. maybe 21-22yrs at this point?

It's been a long run and I'm surprised they've been able to keep it competitive this long.

Ford's Modular (4.6L & 5.4L) engines were available since 1991 until 2014 I believe. Though I wouldn't call them competitive for their entire production run. More of a, we already paid for the tooling, lets see how long people will keep buying these boat anchors.

The Ford mod motors had a lot of changes between '91 and '14 (2V, 2V PI, 3V, etc), no particular engine model lasted more than 6 or 7 years.

That's what makes the '09- current hemi unique, AFAIK, they're parts swappable between a really wide year range.

Here's a nice little video showing the changes to it over the years.
