Hello all! I'm parting a Euro 79 635csi and after researching, here especially, I've found that the bottom end has been swapped from the M90 to an to a US 84 633 M30b32.
I'm curious if anyone has done this before and what kind of numbers this would put out?
I've come over from E30s where there's relatively few M30 swaps as compared to M50 series swapping.

The cam will likely be the less duration head so it will actually be a downgrade. The early 533/633 had the better cam and lighter flywheel.
