Yesterday i measured the timing, because i mounted the M cam and another belt pulley (had to cut the small one)

And waiting for some parts.

Why an M cam?

It's running better in the 3500-4000 range

Really?

The Sport produces more torque all the way through the rev range compared to a Strada and although the Dart with the M cam loved to rev, I always felt it lacking in the mid range. Smooth, tractible, but lacking the punch of my Sport.
