Augi, do you really really think it is going to make any differance ?
Go back to 1978, the days when a "normal carburetor" was no longer, you know the type I mean, a simple carby, idle screw, air mixture screw, points and distributor and copper core leads, authentic Champion or Bosch plugs.
New model cars then had to have tubes and what not plus all this other carpe that made tuning a standard motor car engine crazy.
And for what gain in MPG ? Zilch, infact, worse.
We did things to get by cos the customer wanted a smooth and efficiant running engine for their everyday use, family motor car and the boss had a buisness to run.
They ( the law makers) never asked any of our qualified mechanics what it ( forced changes) turned out to be like straight from the workshop floor.
I can tell ya stories upon stories, but there is one rule for them, and another rule for us...and "them" still wanted their own private cars "rolled back", meaning, remove all these tubes, block the holes and restore as best as we can, on the sly.
Later fuel injection superseded carburetors, this lead was initiated by mercedez benz, mechanical fuel injected V8's, they proved it works.
But laws kept getting squeezed, I got out the game by then never to look back, but that's another story.
I don't recall phrases at the time as we have now, "global warming" "climate change" and what ever else there is, and these forced changes were meant to reduce some sort of pollution hypothesis back then. All it did was add cost to the purchase price of buying a new car.
My point is, if they come down us today( 2008) like they did in 1978, do you really think it will make much difference 30 years from now ?
