The owner said at the time that his car was produced before MB changed the rear axle ratio. From my technical data book I note that the ratio was changed in Sept. '81 from 2.82 to 2.24, a very meaningful difference. While the earlier car would pull redline in top gear the later one would not. We owned a Euro 500SEL that was produced in 1982 that my wife drove as a replacement for a very rusty Euro 450SEL. She frequently complained to me that the 450 was much quicker than her 500 was and peladed with me to resurrect the 450 (she was a very fast driver). Also, keep in mind that the later 500SE/SEL had a taller rear axle ratio than the 560SE/SEL did (2.47). In short, I believe that egutie's 500 could run 155 before the shop work. One question for egutie, was the front cover removed to replace chain rail guides? If so, did they mistime one or more camshafts and/or ignition timing (Euro ignition timing is 16 deg. +/- 3 BTDC with vacuum connected at idle)? Mark

Hahaha i love your wife! she seems like a fun gal! And thanks! about time someone supports me! haha and dont forget pre set 1981 have about 10 hp more!!! and i changed the engine a diff one-- i fergot but i remember the engine i got gave me and additional 10 hp more as well... ill call my mechanic tomorrow morning and let him know about the timing issue, also i have noticed it has been using alot of oil lately due to that! I did get a new timing chain on it and rails ---about hmm 5 months ago...and then the front cover of the engine cracked because a shop next to my house placed the distributor wrong--so i took it away from them and took it to my mechanic i usually take it too...he probably put ebverything back to spec -- as said here-- so ill let him know im not getting the most out of this engine and that i have been burning alot of oil since i got it back! and the car doese not leak oil...sooo its weird..!
p.s. plus the SL linkage that i have gives it 11 rwhp and 15 rwtq...so i know im pusshing a bit more power then stock
