Thanks Pete.

Here is my lowly Mazda B2000 turned B5000





Many unsuspecting victims were left at stoplights wondering what just happened -

Here's an MGB I was working on



No pictures of my old 914 with the Chevy 454.

The only thing I've seen so far that could cause an issue is that the tunnel is narrow in the W108, I like how GGR grafted part of a new tunnel in his swap.

I can't wait till daybreak here so I can hit the junkyard.

Ha ha ha... you put a grin on my face.

To quote Hunter S. Thompson... "when the going gets wierd, the weird turn pro"

You are obviously the man for the job on this small block swap into your Mercedes.

About 15 years ago I did this exact swap into my 1969 280SE using a SB chev and a T350 trans, but if I am to do it again (and I am ;P ) I would use a injected 5.0 from a Mustang.

If you look up Castlemain Rod Shop ( Castlemaine Rod Shop ) and click on the link to Mercedes Benz, they have a selection of engine & gearbox mounts/adaptors to suit various motors, Ford Windsor and Cleveland as well as SB chev.

I hoped this helped.

This information is exactly what I've been looking for.

Thank you Sir.

Some where in my "stash" I have an "Engine Swap Guide" from the late 70's, or early 80's. There is an illustrated article on swapping a Chevy SB into a 108. Here is what I recall. They used a Turbo 350 tranny which fit easily. Today, it would seem silly not to use a overdrive automatic. This bolted right up to the MB drive shaft. To avoid the oil sump problem they used a pick up and pan from a '62 Nova V-8. That moves the sump and was a standard "hot rod" trick in the day. I believe that pan is still produced in the after market.

I will try to find it, scan it and post it. If nothing in a week, remind me.

Here is the result of my home work assignment:

"I cannot be too sure if the mounts will suit your particular car being a left hand drive where as they were more designed for our right hand drive model W108" Per Rods.

Unfortunately this leads to another question thus, is there an engine bay difference between LHD and RHD when it comes to engine mounts?

I think the main difference would be where the steering and brake componants ar located in the engine bay, looking at both of my 108's, one is a 6cyl and the other is a 3.5 V8, the engines appear to locate in the center with no visible lean in either direction. Think the biggest heardle you might face will be the headers.

Mr Quick,
I looked at Ingrid's site and must say after experiencing torque monster engines, (426 Hemi, 6.3MBZ)

Think about the lack of torque of a 302 Vs the weight of the W108 chassis.

The difference of a 302 and a Cleveland 4V is a
lot.
I did a 302 once and yanked it rather quick.

Hey Brian:

Here's my thinking, and please correct me as you have first hand experience.

A basic 302 should have more power than the original 250 right?

So if I start with that then I can do heads, supercharger and as such later.

I do recognize where you are coming from and I am listening.
