M120 is an alloy block but very heavy non the less. Probably slightly heavier than an iron block M117. I had to use front springs from a 450SLC to recover ride height.

The M120 is available in front sump configuration as used in the 129's and mid sump configuration as used in the 140's. I used the front sump 129 version.

At under 3000 and 3.69 I do suspect you will be well into the 12's
