Wow a combo like that is a whole new league of its own,,,,800 feet is an odd number
Not 1/8 nor 1/4.....
Hopefully some of the other guys hear can weigh in..... This is a complex combo.

I would think your driven set up is close, you may need more cam angle. Not formiliar with Dalton spring's but I think you will need more weight in primary. I'am thinking you will need to be over 100 gram's total per arm with the STM's. Better to start out heavy! By the way, what primary clutch do you have,3 arm/4 arm, assuming 4? I'am a little over 90 in my STM's with 215 HP on my Apex (3 arm's). You should be at or over twice the HP that I have.
