Mercules MCF Project Part 4

Two weeks and no updates, we’ve been working on the merc, just haven’t had a whole lot to show for updates.
The engine and trans sitting in the merc. It took a bit of stuffing around, but the mounts are all made. They ended up being relatively simple mounts too.

A recipe for Custom engine mounts
1 X 200mm length of 50mm square bar
2 X 270mm length of 8mm thick flat plate
1 X 200mm length of 4mm thick flat plate
Pair of HQ holden engine mounts
Turbo 350 transmission mount (commondore)
Original Mercedes transmission mount
Original Mercedes engine mounts
The steel cost us a total of $17 and the mounts another $74.

We retained the original Mercedes plates that bolt to the front crossmember, removed the rubber (image below) and welded in a small upright for our HQ holden mount. We went for the holden mounts as they suited the design we wanted for our mounts. Ie would bolt to a 50mm upright.

The transmission mount was pretty simple, a 30minute job really. Cut the original Mercedes mount, welded in a piece of 4mm thick flat plate, two holes and she was done.

burn baby burn

The Mercedes’ engine mounting point was mid engine and on the chev, they are right up the front of the motor. The engineer we spoke to before we started this project stressed that if we could to use the original mounting points on the cross member. Something to do with this already being standard location / strength etc etc…
Anyways some 8mm thick flat plate was used to bring the mount back to the original location.

Next step is to fit our newly acquired Toyota camry power steering rack, modify a sump and pickup, then move onto the headers. We also need to tidy up the engine mounts, trim a bit of fat off them and they’re ready to be painted up.

Not really looking forward to the headers, does anyone know if making headers similar to that on a boat would cause any big issues?

There are a couple of types of engine pipes for boats. One is water cooled and the other is just like standard pipe but instead of going down they rise up and over the rear of the boat, (transom over???). Which one do you mean.

Interesting Work and Engineering guys :)

Good to see the Hitler Mobile progressing.

Not sure what you mean by boat exhaust either

What sort of horsepower you looking for as i reckon you might be able to get away with a pair of rams horns

P.S what parts are you still looking for?

aj510 · 05-05-2008, 01:56 AM

Boat manifold as in something like this

This would be by far the easiest way for us to build the exhaust manifold. Would it thave any detrimental effect on the sound? Not too fussed about power as this is more a cruiser than anything.

Still looking for a sump for the moment.

These manifolds have water running thru them to cool them so as there is a reduced risk of fire ect. The manifold you may be thinking of is called a log manifold. Doesnt do much for scavaging affect from the enginge but they still do the job of removing the exhaust gass to the rear. This is the style of manifold im using, due to the small amount of room I have. Yeah I too recon a set of rams horn manifolds or a set of block hugger pipes might work. Custom manifolds will be expensive.

Here is a pick of block huggers and then a set of rams horn manifolds

FAT-245 · 05-05-2008, 06:27 AM

i reckon try a set of block huggers, but after checking out the photos,
your mounts look to be in the way,

how about having the main primaries going up, then joining at the top then travelling down the back of the firewall, or even channel the firewall to have them sit into it.

Yeah i understand they have water running through them, was more after the style. So it's log style? I think that will definitely be our best option. We've got less room than you had in your bay.

The ram horns and block huggers would hit our mounts unfortunately.

Yeah would prefer to go for a log style, less mods the better. Channeling the firewall would be far too much work to add in some headers on a car that is really going to be for cruising.

Then go Log Manifolds and get them Comp Coated.
