It is just a bad idea all around. Finding time for all the racing stuff is hard enough, now I have to find time to schedule dyno tests and pay for them? How is that an improvement? How much will entry cost have to go up to pay for the dyno the region will have to drag to all the events?
Oh, and I use home built motors and they are not down on power - I do buy good heads though - you can't do that at home without a flow bench.
As stated there is already a spec sealed engine class, FE, if that is what you want go run FE and leave FF alone.
