Unusual Inlet Manifold- Holden Grey

[Shayne]

I've never seen a manifold like this before.  Has anyone got any ideas?  Were they a commercial product, or something done as a 'one off'?? ???

Hi.
I am pretty sure it is a boat manifold. Note the angle on the bases? It is to compensate for the rake the motor needs to be on, for the drive shaft to stick out under the boat. Quite rare, but not that good for a car (Unless it is REALLY jacked up! ;D

thanks Rob,
I too thought it was probably for a boat.  Unusual collectible perhaps, but like you say, not to hot on a road going vehicle :)
