I would start with a 170 main and clip on #3. Adjust air fuel when motor is at operating temp, start at 2 turns out and adjust from there. 170 might be to rich but at least you have a starting point.

.......Cummin's still running on chicken wing grease?

With the K&N I would start with the 170.

Oh yeah, I had a local shop weld on some flat expanded metal and I painted it black. I like the way it turned out, a little different than the rest.
