John,
While it is true that a weight break for the 440s was not among the 18 or so
items asked for in Joe Palmer's list, there were two other suggestions brought
up which had the same intent - give a performance enhancement for cars with
those engines. After considering all of the input on porting and overboring, as
well as soliciting additional input from experienced 440 guys about how well
those options might work, we decided to go with the weight break.
That decision won't please everyone, but then neither would have permitting
porting or overboring. Many writers, including most self-identified 440 guys,
pointed out that porting and overboring run counter to the class philosophy,
and open huge "cans of worms" while complicating the already considerable
clutching challenge. If we were to stick with the class philosophy of "no
internal engine modifications", then a weight break was the most direct route
to giving those guys a break. The CRB recognizes that not all 440 cars will be
able to make that weight, or at least not without considerable investment.
However, neither porting nor overboring are free, either, and either would
require potentially considerable cost to "get it right".
I hope that adequately addresses your concerns.

comment before changing any of these rules? We didn't even ask for a
weight break for 440s. And because a few guys ask and write for
porting for kaws the weight get changed? Sorry but I didn't imagine
rule changes would work like this. Dave Panuef has already worked on
Ti brake rotors and such. This weight change may be well intentioned
for bringing out old cars but aside from the no suspension era cars, I
doubt you could chase 100 lbs out of a chassis without compromising
safety or greatly increasing the use of exotic (expensive) materials.
Just my opinion.

We dropped the weight to 700 lbs after considering all the input on the subject
, especially that from the Kawi guys. Neither porting nor overboring was consid
ered a workable solution, and since many of the cars which came with those engi
nes date from when the minimum weight was 700 lbs, we felt that the best choice
available was to revert to that weight. The change isn't going to make the Kaw
i a Rotax-killer, but maybe it'll bring some cars out of garages and get them b
ack into road racing.
