http://www.edpink.com/news/index.htm there are some prices on two different versions of the toyota motor. Posted over a year ago, but can't imagine they've changed much - but who knows.
Not so sure a limit on rpm is a bad idea - though maybe 9k might be a little high for your average saturday night pushrod motor.
how we were able to think that giving both fontana and esslinger more ci wouldn't be an issue at a later date is beyond me. what now - give the other motors a few more ci to catch up?
as stated in another message, you may have an issue policing some ignition systems - but i think most the motors turning those kind of rpm are not of the magneto type.
regardless of how hard/narrow the tire - thru out time the more powerful motors make it to the front. your just more aggressive with chassis tuning. $$ wise - an sd38 or equal would not be a bad idea to keep tire bills down. a similar compound would be good for lr also.
if motors are the primary $$ problem, which they are, than the motors need to be addressed. A little late for '10, and i'm sure there will be quite a bit of crying but ... if we really want to curb costs and extend life of motors, big steps should be taken - ? maybe no titanium rods, valves - no ti anywhere in motor? sure would limit initial cost, and make sure the rpms remain where they should. valve spring pressure? can't run to much cam or rpm with softer spring pressure ...
the list can go on for sure - bottom line is - no matter what choice/decision is made somebody is gonna feel they're on the short end of the stick. but something needs to be done for the overall health of the sport.
if not, more and more will bipass the midgets, and go straight to sprints. more economic, better purses, etc.
