Don't get the lower ratio - get the 1.47. Most of these had a 19" stainless 3 blade. Some people put 21" cleavers on them back in the day, but would lug them down some trying to plane.

1.5:1 ratio. I ran a 23 Laser 2 which was awesome compared to the 21 Cleaver. She ran 4800-5k at 60+. Can't verify that engine was stock however. The 23 Laser would be equiv to a mirage 21 probably.
