You're putting words in peoples' mouths, I think. At least mine. I never bashed a dang thing. I am usually the first to jump on board the 318 bandwagon. All my point was, that the 273 can be very formidable same as any other engine with the right parts choices. Sure, it's small, but it's not a piece of ****. The D-Darts weren't slow and they were a factory package that's easily improved upon by modern cam grinds and better flowing heads.
If someone already has a 273 and all they want is a snappy little street engine, there's no reason not to use it.
