Just to confirm - Jon Kaase does build BOSS 600s - at least one. It is in my garage waiting for me to solve a driver-side footbox clearance issue. It is a joint project we have worked on since he started to fabricate a prototype for his new BOSS 9 head. Al block, 12.5 compression, one four-barrel on a single plane manifold, and some port work. So far, the best run on his engine dyno was 1,130 horsepower, all natural. It will be a month or so before the installation is done and I will try to post a photo then.

My vote is BOSS 9
