I like the Donovans myself, I'm sure the KBs are fine. Never had a real issue with the Milodons.If you go for a Donovan, it will be their " pro " series now. Very stout pieces.


I dont necessarily subscribe to the notion that gear drives eat up horsepower. The junk ones may.

Stable timing may increase horsepower. That being said, a good quality timing set can do a lot of work in the average race engine. All these things come down to making the proper selection of the correct parts for your application. They all are different.
