Turning what became the family beater into this (http://www.davidson.smugmug.com/gall...50290531_etBA2 - these are really cruddy impromptu videos my friend took, but they give you an idea - oh, and that wasn't blue smoke when cold and that isn't valve tap you're hearing, I have no idea why it sounds like that in the video, if you put your ear next to the valve covers you hear no tapping...oh, and those are 2.47 gears it's running, when I finally get the scratch together for a 3.07 things should improve quite a bit - that's original color Glasurit paint btw) wasn't cheap either (and took quite some time for me to finally get close to finished). Now I just need to raise the redline (will bypass the 5950rpm fuel pump cutoff and utilize the MSD's ignition stutter to set the rev limit to 6400rpm which based on how it runs now should make this engine much happier), map my timing, and do a dyno tune of the mixture, just how much can the MSD cost? That laptop programmable box is like ~400, is there anything else I need to do the things I want?

No idea what else you would want, like I said think I'd be for calling one of the Tech's at MSD. They're very helpful and from past experience I can tell you they will make that box do anything you want it to do. As for the mixture, a pull or two on the chassis dyno will get that set exactly where you want it. I did invest in a mixture gauge and appropriate O2 sensor for this summer's racing.... Mainly to see what temp and weather changes do at the track. Think it might become a standard fixture in most everything I build from now on... Probably a lot more accurate and certainly quicker and easier then reading plugs all the time........ Starting to like some of this hi-tech stuff, I guess....

Lol, I tried to read plugs. I got to the point where I could kind of sort of do it, but at 23 I gave up and decided to go high-tech.

I guess I was just hoping one of you guys know exactly what I need to do because while the first time I called MSD tech the guy knew a lot (and was even familiar with the unique problems of MSD on a Mercedes), the second guy was not helpful at all. I guess I'll try again tomorrow and hope I get the good guy again.

Just tell them you want to speak with someone familiar with the Mercedes systems. Heck, can't expect them all to be familiar with all the different systems on the road today.... I've got a certain guy I always ask for, mainly cuz he seems to understand Ford's on E-90, and he talks in plain English so I don't have to sit on this end of the phone and feel like a complete idiot when I have him explain everything he sez!!!!
