Looks a bit rough, but I'm sure it's a blast to drive! I'd love to do the same to my '84 500SEL, but I'm sure my local Mercedes club would have me shot at sundown.
That’s cool lol. I had a 83 240d that I got for 800 that drove me from Houston to Fort Worth a good 6 times with no issues. Had bought it to LS swap it but ended up letting a friend have it, I regret getting rid of it.
I heard that you have to change the steering box to a rack and pinion system to clear the ls engine. Did you have any clearance issues with fitting the ls engine?
I have a 450SLC and your demonstration of the original acceleration is probably still a little quicker than the original actually was, these were not fast cars. Haha
