Ford 255 dohc 1966 indy motor / 427 sohc?

Question

Why did the us automakers not use this technical info along time ago ? We watched the jap motors take over the economy market and all we did was make a crappy pinto and vega motor.

Answer 1

Blame it on the insurance co. and the first Arab oil embargo

Answer 2

And it wasn't just the Japanese that had good drive trains either.

If you were to look at the German engines the first overhead cam engine was a huge success. Later the only thing you could find was OHC engine. Economy? They were the best. MB200D was a simple two liter diesel got 35 miles per gallon highway and 28 city in a very comfortable 4 door sedan. Had one for 35 years and put over 800000 miles on it. yes five zeros. It was a great car it was to bad someone hit it in an accident and totaled it or I'd still be driving it.

Just like today the American auto industry is being caught with their pants down by not having enough economy cars and are stuck with huge inventories of SUV's that they can't hardly give away.

OH well. Maybe the GM hookup with Renault/Nissan will at least save the GM logo. I doubt that it will save the brands. Olds is gone and Buick or Pontiac will be next. Remember you saw that prediction here first.

Answer 3

Ford Dohc 427

Answer 4

DOHC is not the answer to all questions.
Yes, American automakers are moving to it or already have.
But there are drawbacks. More parts , higher cost, more space
is taken up in the engine compartment making cooling a pain,
and some consumers do not like the lack of low end torque.
I think variable valve timing is one where the domestics were too
slow to invest in.

Answer 5

The "Cosworth" V8 is still used today in Formula 1 cars. The single-overhead-cammer was also a "race" motor.Same is true for the mighty "Boss 429".

Answer 6

it takes more than a great engine to create a great automobile
efficient drivetrain, transmission, etc. is required
