Anyone need some Alpina race engine parts?

its a shame that clown is busting that engine up, next-to-impossible to find complete, let alone assemble from multi-sourced bits.
my guess is that his gambit to maximize $$ will backfire, how many people would all concurrently bid to win the essentials of that pile o parts, versus the risk of "winning" all but two ro three of the essential bits?
sigh, what a way to take the shine off of a hobby

I can just agree that it becomes more and more difficult to find a complete engine of this type today. I guess that the seller figured out that selling the engine in parts would be more successful than selling the engine complete.
There are some major engine damages and some important engine details missing, but nevertheless, finding all these parts all togehter at the same time is not very common. I am just very confused that the seller does not mention the engine number stamped on the engine block and the number on the cylinder head, that would have been very important information to be given to a potential buyer! At a first glance this might be a assembly of parts coming from many different engines?
I hope that the parts will be used and not being stored in someones basement.

Beside the injection-related items, and possibly the camshaft and/or the head, I doubt any other part is from a original 3.5 M52/3.
The oil pump is definitely not Alpina.
The casting on the bloc shows it is from 1982.

um...the M52/3 is a more modern engine, isn't it "VANOS"?
Perhaps you're thinking of the M49 (M49/2?) 3.5 developed "for" 1974 ? That was twin cam I believe, and a BMW Motorsport engine. It also used a different mechanically-injected slide-throttle setup than Alpina's.
For a couple (3?) years Alpina used its slide-throttle injection on single-cam engines. Privateers with $$ could have too, along with slide-throttle setups from Schnitzer and BMW M-sport after '73. I dunno anything about Alpina and twin-cams in the CSLs, but I'd suspect they started using the Motorsport stuff by 74.
Anyone have fotos of a dry-sump set-up that is "definitely" Alpina?

The M52 label was use twice.
The first time it was for the Motorsport engines of the CSL in 1973.
M52 --> 2996ccm - up to 330hp
M52/1 --> 3.15 L not used in races
M52/2 --> 3303ccm - up to 355hp
M52/3 --> 3498ccm - up to 370hp
Alpina and Schnitzer developped their own race engines from the M30, and these should in principle not be labelled M52s.
But it is common practice to name M52 all 12v CSL engine from 1973 to 1975.
The Motorsport and Schnitzer engines have the oil pump inside the sump, the Alpina engine has it outside.
The injection pump is always front left on Schnitzers, front right on Alpinas, in the back of the engine right hand side on Motorsports.
The Schnitzer engine has a special water tank, bolted directly to the engine.

The M49 was the 24 valve evolution of the M52.
It first appeared in the 1974 Motorsport cars (the dark blue ones).
M49/1 3.3 l 430hp
M49/2 3.5 l 440hp
During 1975 Schnitzer very cleverly re-engineered the M49 into the M49/3.
Thanks to the vertical position of the engine the induction path could be made straighter, and the exhaust header could be made much more efficient.
Power climbed to 480hp.
