There is one 300e engine that probably is overall the best rated engine out of them all, a european 300e , higher lift cam and bigger pistons . I wanted a 300e and I searched everywhere the only one I wanted was a euro though. It took me 6 months to find it but I did. Paid 2000. for it and went through the engine and modified the pressure orphace in the valvebody to make the shifts long but quick . We put the car on the 1/4 mile meter and I am running high 14's . I am gonna take this engine out next year and build a turbo and see how it does. If you know a good Mercedes transmission tech he can do modifications internally on the valve body and make a big differance . When I did mine it was trial and error ( took 4 times to get it right ) . I love this car , I will change my rear diff later and see what happens with it . By the way the fastest I ever got this car was at 147mph so far . Kinda nervous over that. We are also working on my stainless steel exhaust now with custom muffler and resonator.
