360s will be the end of Selinsgrove as a sprint car track.
I think Pa will see a migration to smaller less engine dependant tracks.
It's time for the tracks to develop a 5 year transition plan that introduces a larger cubic inch motor that creates roughly the same HP (around 650) as a 358 to allow a natural migration.
My fear is that tracks will take the easy path and change to 305s as support... On the basis of how many are out there and the misconceptions about their costs.
True engine cost reduction needs compression and rpm rules. The cheapest HP comes from cubes.
the problem i am seeing is yes, there are 25k 305's out there now and the 305 class was originally started as a spec class with the idea of being able to take your 305 anywhere in the country and race. it has already gone past that idea and have a lot more rules and politics.
here is one stupid rule (yes, there are more) you can only use Ti hardware within 2 inches of the center of the rotating assembly.....which leaves out Ti wheel bolts, beadlock bolts, hub studs, ect but you are allowed to run a Ti driveshaft at $750.00 and Ti hardware anywhere else on the car...WTF?
i know for a fact that there are 305's out there that are dynoing over 150-200 hp more than the majority.
so....what started as a laid back, everyone gets paid class is quickly morphing into every other spec class that has been tried and didnt work.
i DO like the idea of a spec big block. give the builders a little room and then seal it up and race it.
not only is there no substitution for cubic inches but it allows more time between rebuilds caus you are not screaming the crap out of it trying to make HP.
