Thanks,

They along with the end of the prechamber go into the cylinder and eventually out the tail pipe. I just put up a thread about this. Replaced 2 of 3 faulty chambers and the car has some real power now. Can't wait to properly torque one of the 2 and redo the other one as well.

I will let you guys know of my experience as soon as it is done.

With limited highway grades, you'll be fine. The fellows on the flatlands love the 2.47...........but, it won't climb a decent grade at speed in fourth.

My 2.88 will need maximum power to hold 65 on two specific hills in CT........and I never considered them very steep.

I put one in my '83 300CD and love it! At 75 MPH the tach is about 2900. I am having no problems with hills. I expected that I would have to bump it down into 3rd much more often than I do. I drove it from High River, Alberta to Likely, B.C. and back recently. Google both locations on Google maps if you are curious what sort of a drive it is. 2 very full days in some pretty rugged mountains. I got such great fuel economy that I MUST have done the math wrong.(BUT it is GOOD) I couldn't be happier with the lower revs and quieter ride. Of course I really have to admit that I now would like more power too, but it doesn't need it. It isn't 'glacial' like I a 240 (no offense intended 240 owners) the urge for more power is just the kid in me.
I checked the speedo error today with a borrowed GPS. At 100 kph I am doing 121-122 kph. had thought it would be more like 124.+ kph but the speedo was probably reeding a bit low before the swap. Now I need a good speedo out of a 380sec or something else with that 2.47 diff
Good luck with your swap
