Looking from the cockpit forward, you want to angle the spinner right slightly and downthrust. Most trainer kits have the downthrust built into the firewall installation. If not, put a 1/16" thk. washer between the top two engine mount holes and the firewall.
I hope it was a typo when you said you were putting a .40 engine in a sixty trainer.
No, it wasn't a typo, this ond trainer was designed for a .40 as a minimum or a .60 for more performance. Since I have the .40 sitting around that's what I'll use to get used to things again. Since I didn't get the construction manual, just the plan and I didn't do most of the fuse construction, what's the easiest way to check to see if the proper downthrust is built in or not?
