450SL Engine Mods?
Hey everyone!
I'm new to this forum and figured I would try it out. In a couple of months (early feb.) I will be inheriting one of my childhood dream cars - a '74 450SL
.
The car is in great shape looks-wise and the engine is in good shape for how many miles it has on it....nearing 200k!! (it recently had a valve job and tune up)
I plan on fully restoring the car (interior/exterior) but after driving it a few times, I would love to put more power into it. I'm not at all mechanically inclined but everyone suggests that if you want more power, than swap out the engine for a 500 Euro or possibly a 560 engine (maybe even a M117 AMG Hammer?
) ? Modifying a 450SL engine is apparently SUPER expensive, and replacing the engine is a lot less expensive- if you can find one.
What is people's take on that? Considering the high mileage, I will likely have to consider replacing the engine in a few years anyways.
I love these cars since I was little and can't wait to own one!

A replacement always seems like such an expensive way to go. This may provide a few lower-cost things that you could do:

You're welcome. If I ever find a way to put a Kleemann blower on one of these old motors, I'll be the first to start a thread.

haha, that would be sweet!
Nice 560SL by the way.
I stumbled on this article over at benzworld.org and found it interesting. http://www.benzworld.org/forums/r-c1...50slc-amg.html
The guy purchased a modified '73 450SLC and listed all the restoration/ upgrades he has done on the car (including web links). I found it to be pretty thorough and seemed like he knows what he's doing.
Anyways, thought it was worth sharing.
