Dear forum members I need your help, I have a 1980 635 w/ a blow engine. The B.M.W. specialty shop that is doing the repairs told me that, cranshaft and rods were damaged. They are going to take the crank-shaft/rods to a machine-shop to get them " miked",to see if they can be re-worked. If they cannot reworked they informed me that it would not be worth rebuilding. They also told me that that my cylinder walls in resonably good shape and could probaly getaway without getting my block bored.

They told me that I should consider putting a block out of a 87-88 735 or a 90 735(is supposed to have high compression).


My questions are: Should I consider putting an american block in an euro car? Is it worth spending my kids college money on a complete engine rebuild?

Will I notice the loss of power? Is the specialty shop trying to encourage me to which blocks, so they can get my euro block (arent they rare)?


What is a resonable price for a complete rebuild? What is to much to spend on a 80 euro? Where can i locate euro engine parts?

If anyone has had any experience rebuilding a 6 series engine I would greatly apprecaite your input.

THANKS IN ADVANCE
