That’s killer. How are the Ritter blocks nowadays? The one I got yrs ago was a dud.

I don't have one but from what I hear today's Ritter blocks are fine.

The seem to be a good substitute for the now hard to find R3 blocks.

Brett could tell us more as he has built several.

Great power number, and at a lower RPM then I expected.
Pretty high RPM for the torque peak. What was the torque at 5500-6000 rpm?

The torque was really flat on that pull we got it too rich at peek torque and it knocked in in the butt.

Most pulls peek torque was around 6500 ish.
