    should gain peak torque in proportion to the change in engine size. lowend will be alot better yo, but without breathing mods the gains in peak hp might not be as dramatic as lower in the rpms

    Correct. It is a punched out M50 with more cam, and I'm sure a little tuneage. Head casting is the same I believe.

    I believe those are stock numbers. I'm sure someone else with more knowledge will chime in, I'm a noob. I believe the M50b30 was the US M3 engine?

    No, the US M3 engine in 1995 was the S50b30. It had different cams and engine tuning but was still very much based on the M50tub25. An M50 with the same displacement but 'weaker' cams and a more mild factory tune won't make S50 numbers.

    Take parts out of this block and install in your B25 block. That's it, all parts fit.
