Come on down to N.C. 93 octane Ethanol free gasoline is under $4.00. No Safety Inspections or Smog Checks for 30+ year old cars. Some counties like mine no Smog Checks for any vehicle. Ultimate freedom is to find a nice house without an HOA. Use to have relatively cheap houses and land but that has changed dramatically in the last couple years.
$3.69 this morning for 93 Ethanol free in Summerfield NC. Still too much but not as bad as elsewhere.

Nice more HP than my M120 V12. Did you like the sound of my exhaust. Vibrant 3" muffler with resonator. I would expect the V8 to be a little more throaty.

I had to go with a 2.5" dual inlet and I only see the Vibrants with single 2.5 or 3" inlet.
Its seriously fast now but it still doesn't feel as quick as yours to me. That 722.6 makes huge difference, this winter it goes back in for one, then we'll see.

Its unlikely the 722.6 by itself will make any difference in performance as far as 1/4 mile times or anything below 120 MPH. But it will make a huge difference in fuel economy and be a lot nicer cruising down the highway with the engine barely running 2000RPM. And if you want to gain performance you could put in a 3.06 or bigger rear gear ratio while maintaining your current fuel economy and cruising RPM. The 722.6 is a beautiful thing all pros no cons. I'm temped to put one in my stock 560SL.

Roncallo, sorry to threadcrap and cut in. Was reading through and didn’t know we had another new member to the 107/V12 club. I’m fascinated, will never sell mine, and always have the idea in the back of my head that if I finally wear-out my 5548cc piece of wonder, well, I’d attempt to use your instructions and posts and have something similar done to mine.

Anyhow, I actively tour with mine and am fairly sure my current 204k mi will see 275k before the engine needs to come out, and your comment regarding a 722.6 with the stock engine.

Could you give me some rough estimate for the difficulty of a tranny swap? Like, just a quick “1-10 scale” or “extreme pain in the ass” or not.
I haven’t a lift nor probable welding skills, but was just trying to guess how many hours labor if I were paying a trusted shop $110/hr.

If driving it back to my driveway counts, then I drove it, but honestly @1783pictures drove my 280sl more than I’ve driven it in at least a year or so today. We did the obligatory drive past Joe Biden’s house and through a couple twisties while I was in the passenger seat. Too bad he doesn’t know the roads better and I didn’t have time to air up the really-low front tires.

1.36 per Liter?
It's Canada. Do you really think we'd get a gallon for that price???

How the hell would we pay for our health care??

C$1.36/l is for Regular. About as high as we have seen. It is equivalent to about US$4.00/gal.

Last time we wintered in SC, gas was about $2/gal.

With US gas that expensive, we will just have to stay home. Factors like a pandemic and the border being closed may also contribute ;)

We Yanks will trade our Politicians and law makers with you Canucks ... how much boot do you want?

Course you're getting all our Lobbyists, Lawyers, Congress, and all the special interest folks. Take idiots like Sidney Powell and Rudy Giuliani or its no deal :)

Ca$1.36/l=US $5.15/gal. In WI, we pay about $4.00/gal for Premium. When I was doing expedited freight, I filled my truck with diesel in ON once. After that, I filled it before I crossed into Canada.

Hi,

Here in Germany the price of gasoline is also very high.
98 octane 1 liter = 1,69 € = 1,96 US $ = 2,48 Canadian $
1 Gallon = 3,785 liters
= 7,42 US $ for 1 gallon
= 9,39 CA $ for 1 gallon

Took The PIG out for a spirited jaunt through the Laurentians yesterday....leaves have almost 100% turned.

I LOVE Fall drives.

Had the heat on....my $650 monovalve is working great!
