How about a BMW M60?

I had one of these in my E38 740 and it pulled like a train. The engine is still about funnily enough my mate is making a manual 7 series v8

I reckon the bloke who built those manifolds needs to concider flow and shockwave issues on the markII versions.  :o

no, definitely Gen-III Chevy, not Northstar.

The Northstar is absolutely huge and was designed for front-wheel-drive (yes, really), so doesn't readily adapt to correct-wheel-drive. I did a Northstar installation back in 1996 for a company I can't name on here, there were no rwd Northstars available then, so I had to design a bellhousing for them. I believe that there is a Northstar now available with rwd, so at least the bits are available. Cadillac STS ?

Not aware of any other rwd Northstar conversions around. Certainly all the fwd donor vehicles need to be hooked up to the 4T80 transverse gearbox for the electrics to work - much more difficult than with an LS1 (at least an early one anyway)

The "original" manifolds for the Omega V8 were tubular - you have the correct pics, but these may have been low-volume pre-production items destined to be replaced with cast for series production. Any way up, I have no fear that current after-market "tight-tuck" manifolds can be made to work with the Omegas steering box.

The clearance pictured isn't that bad. In the region of the manifolds, the engine movement is "up/down" and not "side-to-side". 3/4 inch is good enough for clearance under all circumstances and to slide a heatshield in.
Probably a silly question as i have no idea how the steering box is installed, but is there anything go be gained by moving the steering box over? How is it fitted? Guessing the universal joints in the steering colum will allow it? And track rods could be set up out of center to keep the pitman arm straight, i'm fairly sure....? :-/

I reckon that's a non-starter, TBH. ;) Moving the inner pivot point of the track rod will make it handle like an underinflated, badly worn Falken on a bad day, for a start.

Ah, will need a longer centre tie rod.  :-[

The problem with the steering box re. movement is that its a lot of work. The handling is very sensitive to the effective track rod end position, and if i was going to put the effort into a re-calculation, I'd prefer to spend it on a rack

the manifolds would be of the non-interference type, so runner lengths, etc. aren't important.

The BMW engine is a good one, but probably quite wide, and just try finding one in the aftermarket with a manual box.

And fabricating manifolds to the space available simpler still?  ......  By comparison?

Isn't the pre production V8 Omega languising in the Opel museum in Russelsheim? At least it was until fairly recently.
