How much is M50 shortblock and head worth ?

[Jean]

What's the going fair rate on a used but working/good condition / average miles m50 block and head ?

[FredK]

$400.

You will pay out of the yinyang to complete the engine with

Harness $100
Manifold $100
TB $40
Alternator $40
PS pump $40
ICV $20
Engine mount arms $30

That takes you to $390, and you still need a DME ($120 - 150). So, not worth it unless you already own an E36. For swap guys, get as complete an engine as possible.

[Jean]

So $400 for the block and the head + the parts you listed ? Not too bad, but it would make more sense to just buy a complete e34 engine right ?

[FredK]

Yeah, $400 is a good price for just the block and head.

It'd make more sense to buy a complete e34 or e36 engine. The e34 oil pan is getting harder to find for a reasonable price, so you might be better off getting the e34 m50.
