I've picked up an Australian delivered 350SEL, 293,000km and pretty rusty.
I'm keen to convert my 280S to V8 and this seems to be a perfect opportunity but I want to run a carby.
The D-jet is currently not operational and I believe I will go down a rabbit hole of effort and money getting it running right. Putting fuel directly into the manifold sees it running with great oil pressure and no smoke. Compression test is 160psi minimum on all cylinders so it's pointing to a sound motor.

I have a suitable carby from another project so the only thing stopping me is an inlet manifold to suit a carby. I've seen adapters on the standard manifold but they seem to really deplete any performance an economy. Custom manifolds seem the way to go but is beyond my fabrication skills.

Anyone know of any manifolds available?

I will be parting the car out, located Perth Western Australia.
Colour is 623H - Light Ivory but has been resprayed at some stage

Today I replaced the fuel filter with a cheapy, replaced a couple of fuel lines, put in $20 of PULP and it fired up!!! Idles and revs but a bit rough as expected.

I've had no luck with manifolds etc so I'm not going to do the transplant. I'm wrecking this car now, anyone interested in the 3.5 motor and wants to see it running before I take parts off that will stop it running?
Let me know if you need anything.
