Different between an '85 M20B27 and an '87 M20B27?

[seven-57]

Just wondering what the differences are if any. I'm looking at picking up the '85 M20B27 as a donor/parts motor for my own.

The engines are the same. Though the 85 will likely have the stamped cam and intermediate shaft sprockets. which you don't want to use.
