Identify this engine
 

I've just purchased a '66 912 and can't seem to find a match for the engine that is in it. If anyone could identify it for me, I would greatly appreciate it.

Thanks in advance.

Type of Engine
 

It's a VW Type I/II dual port. Feel around back on the driver's side to see if there is a 'doghouse' used to encase an offset oil cooler. If it has a doghouse it is a more recent motor. From your photo, it is interesting in that the rear motor mounts do not appear to be used: the rear of the motor needs to be supported (there does appear to be something happening below the mounts...).

The rear mounts are hard mounted. There is a bracket below the crank that goes across and then two pieces come up where the rear engine mounts are and bolted to the brackets for the engine mount instead of the mount itself.

Is there a casting mark, etc that will identify the exact type of the engine so I know more of what I have got?

There is no way to tell what you really have: the engine looks to be a hodge-podge of parts. Just by the picture, you have a fuel pump meant for a motor with an altenator (canted away from the generator to make room for a larger diameter altenator), what looks to be an 009 distributor, after-market dual carbs (AFAIK dual ports only came with a center-mounted single barrel Solex, witness the block-off plates on the exhaust heat risers), an electric fuel pump hot-wired to the coil (which is dangerous in the event of accident - needs an inertia switch). If the case has two mount points either side of the pully/oil pump, it is most likely a universal replacement case used for either Type I motors or Type II with rear mount. With the motor hard-mounted to the chassis, the mount and/or mount points will eventually fail due to vibration. You also have a throttle cable; 912 linkage is all rod with ball joints and bell cranks (one on the transmission near the nose and one on the back of the fan shroud).

A popular upgrade to dual port motors were big bore kits from 87mm to 92mm depending on slip-in or machine work (85.5 was stock for the 1600): no way to tell by looking.

OMG!!! That's a code 41-4 Side Carb VW/Porsche/Audi/Skoda/Vaxhall/Simca experimental!
A rare 450HP OHV port & polished, chrome plated, heavy waxed piston domed speed motor! Guaranteed not to rust, bust, or collect dust, and at no time do the pistons ever leave their cylinders!
I hope that helps.... (I drink a lot!)

Appears Volkswagen. To determine what was originally there, can you give us the chassis number?

Thanks,
