I have a Pred 212 that I reworked similar to what you did plus I put in a mild cam and 18lb springs. It is a CL-2 and I put on a ARC billet flywheel.
WOW. Big difference in power from stock. That cam isn't even supposed to be that good but it made a difference. There are plenty of cams you can get for not much money. Mine was $12 used... I also disabled the governor to let it spin faster. You can get a tach and watch the rpm. I heard not to go over 6000 with a stock rod.( Also from what I heard the CL-2 cam won't spin up that far).
With 10:1 gearing and a governor your not going to get much top end. When you hop up a Predator you get a lot more torque and can change your gearing to take advantage of that. I'd shoot for about 7:1 to still retain some out of the hole grunt and gain some top end.
The problem is once you start modifying the engine, you are always going to want more power, then more power ... etc...
Have fun
