I agree 410 no rules, my only issue with the 305's is the simple fact that it is not reducing cost sure I hear about the 5-6,000 notors but I also see several companies in the 12,000-13,000 and at least one offering a motor at 30,000, oh and a new 305 rear end . It is not simple to limit 360's and the guys that will press the limits will spend 45,000 a copy for a hitter with all the 305 rules some will pay 30,000 for a motor. I think it is very difficult to create an enforcable yet easy to tech package

From Trostle book,  they used to go to GM car dealers and buy short block  assemblys for $450.00.  These were the high perf. short block that they put thier heads etc on.  This was in 1960-1970 s.

That's why the post states "use/rebuild"  ... limit the number of rebuilds to 5 (or whatever makes sense).

You would see instant longevity from the motor builders = Cost Savings

It's as simple to limit 360's as it is a 305.Compression is easy to check,and restricting air intake is easy to check,as simple as a restricting intake gasket.There are still more budget built 305's out there than the hi dollar engines we hear about.The WoO is the premier class,they have the sponsors and team owners with big pockets,let them do their thing,they can afford it,but the 360 class has gotten way out of hand,what started as a budget class with a souped up engine out of a chevy truck has turned into $40,000. big bore short stroke engines with aluminum heads and hi compression.The only difference between the current 360's and 410's is the cubic inches,choice of heads and aluminum blocks.

After reading this thread for 4 or 5 days. Can someone list by parts that go into a 410, ASCS 360, 305.

By Crank, Rods, Pistons, Rings, Bearings that is the bottom end. The bare heads, full done head with valves, springs and rockers.

Then heads with the cnc porting. Push rods, Gasket set. Then the put the motor together price.

Then how much it is for the dry sump parts, Pan, Pump, Lines, Tank, Water pump, front plate.

Thanks

You would actually see more motors break = more expense or more teams not running later in the season.

Also rather hard to enforce. There are already teams cheating with sealed 305 motors!

 
 
 
They don't even know how to spell sprint car

I totally disagree, there are many more 410 winners and more cars in the puts that have a chance today than there used to be. There were how many years when Kinser, Swindell or Wolfgang won nearly every WOO race. I remember gping to the races in PA 15 years ago when ther were only 3-4 cars in the pits that won all the reaces. There's a lot more parity today and teh cars are a lot more equal.

i personally would like to see an alternative 410 class that i think any local track would be able to adopt and run a weekly or biweekly series. 410 with iron block,iron heads,wet sump,spec roller or solid camshaft,pedestal rockers,5.850 rod,and maybe even a 2 13/16 injector that could be adopted as spec with a specific manufacturer involved as a sole supplier that would support the series with possible cash support? some injection systems are out of most racers hopes of being competitive. i believe with the proper support and enforcement this could be a great alternative and much more affordable class, even run the more cost effective old skool mags that dont carry a msd pro dollar price tag. good solid power and perfect steppin stone to a pro 410 class in my opinion and it could be built for far less than an ascs engine hands down. 305 classes are fine but too many rules from track to track............alot of budget guys could be headline guys at venues everywhere if you keep the pro level equipment out. 410 show without the high price.....increase car count, not kill it. JMO...................i would put this engine in both my entries and run...........

I was there in those days, and yes there were dominant winners back then, also. But the reason for their dominance in many cases was due to their know how. They were the inovators that brought us to where we are in terms of making a sprint car go. They built many of the parts in their own shops....adjusted boughten parts as they took them out of the box. As the knowledge they attained spred, manufacturers and engine builders became more advanced, also. Now, it's simply who can afford to spend the most and pay for the highest output motors and keep the freshest parts in the trailer. The seperation in todays fields is the money factor, not the skill and know how factor. Bring the money factor back to a balanced amount and we will see better racing.

  Good post Blazer!!  I agree 100%

Hey Kelly, good to see you post.  What's the answer to the 360 dilema?  NSL wants to limit the head work advantage.  Most grassroots 360 racers would like to see that too.  I've heard their toying with a gasket with a pretty small hole in the intake.  I have no idea if that's true or not.  Not sure I'd like that as it would make it a one series motor only.  The other issue is oversize motors.  You know as muich about 360s as anyone.  What would be a good fix to bring them back so older motors can be competitive again?  Thanks.

Most of the parts should start getting cheaper like a VCR, DVD, Computer. etc. Once you pay for the R&D work things get cheaper.

Now there is only one step left in engine development. That is valve springs being changed out to what F! and Indy Car used Air Springs insted of coil springs. Then limit the RPM to 9000. Time for the MSD box and chip.

Narrow tires and wing angle just make them go faster. Got to do something with the side boards and wicker bill.
