1969 W108 280SE - Chevy 350/T-10

Hey everybody, So I picked up this 1969 Mercedes 280SE W108.018 last June with the hopes of completing it by the February, obviously I missed my target by a few days... Well now I am setting aside my prior problems, mainly procrastination, and am finally hitting the car hard now. I built and blueprinted this SBC 350 last May and have just picked up a Borg Warner T-10 a few days ago.

I will let the pictures do the talking until I have something to say or someone has a question.

Just realized I don't have any good pictures except for this one from the night I bought it...

Por15











Cam Bearings




Installed Cam




Balanced Crank




Setup




NASCAR and Porsche only balance to 5grams out of balance, I later got it down to 0.5grams but didnt take a pic of it.




Install Crank and Pistons









Cut seats and assembled the heads.

















Got some pics of the porting, sorry for the crappy blurring and focusing my camera was running out of power.








Intakes are just pocket ported, Exhausts have a full port. Both intake and exhaust ports were port matched, De-burred and the "Cliffs of Death" were removed and smoothed out.

Took off the TBI Manifold that was just covering the valley.



Put on the Carb Manifold and indexed the new bolts.



Installed the new HEI Distributor, sorry it was getting dark.

Just ordered the last of the parts to get the engine running except for the drive belt assembly and alternator. In the past few days I have also purchased a Borg Warner T10 with aftermarket internals and a Hurst shifter as well as a bell housing, flywheel, clutch linkage kit and clutch kit.

I will be getting back into California on the 10th and plan on hitting this project hard so that I can finally enjoy what I am sinking all this money into.

Nice build pics, but why would you do this to such a fine looking Mercedes? You could have used a 5.0 from an SEL or SEC at least instead of GM iron. I don't understand, but have fun anyway!

My only question is why would you switch to fuel injected heads but then use a 4 bbl intake?

Top five reasons I posted in your topic:

1. You're talking about god, there has never been any god of any kind. EVER!

2. I just have a general dislike of you.

3. I am trying to tell you how to fix your Mercedes and you are not listening.

4. I'm flirting with Jody.

5. You're just to dumb to own a Mercedes, and should go buy a Honda.

Ohhhhhhhhhhhh yeah! A naked engine is a thing that gets my blood pumping! I TOTALLY support this swap! Not only is the engine more common than one from a Benz, but imminently more upgradeable and at much lower prices! Have you thought about a blower? An Edelbrock will fit right into the V and give you a ton more HP.

What are you doing about the steering? Oil pan? Maybe you mentioned, but auto or manual tranny?

It honestly isn't as nice as the pictures make it look, the body was Maaco'ed a few years back and the interior is on its way out, also the engine is basically dead now and that is why I bought it, I would not be doing this to a nice 280SE. Now for the engine... I am a college student, and although something like an M117 would be an easier swap in the respect that it is a front sump engine and that it would be more of a purist thing to put another Mercedes engine in, but I cant afford it. The Small Block Chevy can put down as much power as I need it to with just as much reliability at a fraction of the price, also the price of mating a manual trans to an M117 would be astronomical.

Swirl heads were TBI not MFI so they still had almost the exact same manifold as this carb manifold. Also I went carb because I wanted to eliminate as much wiring as possible and just keep the engine simple. I have wired to many engine control harnesses to want to do one on my own car.

Converting to a Rack and Pinion and a modified crossmember/subframe to support the rear sump. Borg Warner T-10 is a 4 Speed Manual.

I understand. BTW I'm interested in your project. Also a Chevy fan. A simple engine compartment is soo much nicer looking to me too.

You should see my 454SS's. I got a 750hp supercharged 454 I'm getting ready to put in one of my 90's.

This is my white one.

And the new 454 that's getting the supercharged engine.

I see your work is right on par with mine. Like the project, keep us posted please.
