Harley V-Twin?

Usually gets reinvented every twenty years.

Usually gets reinvented every twenty years.

Yet they still leak, rattle, vibrate parts off, and generally suck, IMO.

Buick 215 Aluminum V8 went from 61 to 2004 and the vast majority of parts still interchanged despite being built by GM, British Leyland, Land Rover, and BMW over the years. V6 went from 62 to 91 before they really changed it into something that the parts stopped swapping between. Stovebolt 6 went to Japan and lived on in the Land Cruiser till the 90's did it?

This discussion raises lots of interesting questions for me.

One of which is, why do the OEMs now piss through engine designs every few years when there is a pleathora of proven designs out there to at least pull pointers from.

Good stuff gents!

Emissions regulations, and Corporate Average Fuel Economy requirements.

Re: Question: What domestic engine lasted the longest with it's original design?

Definitely is one of the more interesting topics of late. I've wondered it myself...what is so hard about engineering the problems out of the engine, instead of going to the clean-sheet design? Gearhead's hindsight proves you can find the extra power that should have been there all along, the reliability issues can be addressed as time goes on...it seems like such a no-brainer but sometimes you have to wonder why the do what they do.

How long has the OHV Briggs and Stratton been around?

Briggs and Stratton engines are as bad as the Harley engines...you think it's the same design but the internals are changed. The longest-production one is Model 80200, a horizontal-shaft block that ran from 1960-1997.
