The 410 has been upped to 440 cubic inches.
Specifications for the "Knoxville Open Sprint Engine":
Maximum Bore 4.165 (4.00" stroke = 435");
Maximum displacement 440 cu. in.;
Maximum intake stack I.D. 2 5/8" for minimum 4";
Maximum header size 1 7/8";
Minimum 15 degree valve angle. This allows -12 (Brodix model #) 15 degree heads /16, 18 and 23 degree heads. This will make the GM crate 427 engine legal

I'd rather be in Knoxville.

Thankyou Knoxville for helping to keep Sprint Car racing alive in Iowa...The little guys may now be able to step up from other divisions.

I'm guessing that it is legal only for Knoxville weekly shows and will not be allowed to run the WoO shows? What about the Nationals?

It looks to me that it will be legal all shows all season... Sounds good if that is the case..

If people cannot afford a 410 how can they afford a 440?

What's to stop people from spending just as much money on a 440 as a 410? Are there rules keeping out lightweight engine components?
And WHY wasn't this announced at the end of last year? Anybody who's competitve is ready to go by now.

WoO shows are run under WoO rules; I don;t think that a 440 will be WoO legal.
So if a bunch if Knoxville cars buy/build 440's, how can they hope to enter a WoO show.
But since the Nationals is an unsanctioned race, the locals can probably run them there.....

interesting topic, ironically has sparked my imagination lately, agreed, why wasnt the release made plublic months ago? Ive been digging around the internet here and dont see the 427 crate engine of much comparison VS a "outdated" ten or fifteen year old sprint 410 (750-810hp) are we talking SBC or BBC? all i found was Hydrolic cam? ya right, cast block? I dont think so, maybe im missing something? somebody give me a list # so I can make a semi reputable comparison , still looking for the "real" compairable 427

Like how much cheaper is this 440 motor going to be over a 900 HP 410 light weight motor, does anybody have any figures on cost savings yet.

Those GM crate engines are pretty reasonable. I think an LS7 which is the small block 427 is around $12,000, but that's a 505HP engine. Would require a lot of work and money to get the HP up to compete with a WoO 410. I don't understand the idea behind this at all, but I'm not a gearhead or a rules-maker. A

It may be 440 cubes, but they're choking them off on the stacks and headers, so 900hp will most likely be out of the question.... Farmington has been running weekly 430's for years, with no restrictions....

It might all simply boil down to politics and money. If there is a fair group of 440 cars running Knoxville weekly, that don't pose a threat to the big $ WoO teams, WoO could always bend a rule to allow them. Higher car count, more local fans buying WoO tickets, and the same drivers winning- why not?
WoO not working with Knoxville to accomodate the weekly racers might have some painfull ramifications come Nationals time.

The reason they just announced is because it was just decided on Monday night...they are not expecting many of them to be ready for this year, maybe a few mid-season...and knoxville is not alone on this, they are the first ones announcing. Several other weekly 410 and 410 sanctioning bodies are aware of this and are planning on following..They don't expect this new motor to neccessarily be able to win at kville, but they will be competitive and with the restrictions, very cost effective. What they want to accomplish with this is to have more teams moving up from the 360 ranks. I think they are even going to drop the 410 name and call this class the "Sprint" class or something like this...

I personally have a struggle gaining more HP from a outdated 410, on a local level my mill is responsive and competitive, although to run the larger tracks competitively, a much more expensive top end would have to be purchased , with heads, injection, and correct pistons im gathering up a additional $8 to 9k? so, upon freshening a larger slug is another $700 - $800 , my block is reusable with more machining and im back in the hunt, possibly guaining the 50-70 hp I need to get back in the game, trouble is, not many of us "blue collar racers" exhist , most teams are well funded , and us lil guys pick up thier broken pieces, the additional (440)rule is good, it has a point, (ok, so you can still call it a 410 who cares) if you love sprint racing this is a avenue opening up the top class to new drivers and underfunded teams , with a head and injection rule in place on the 440 the benifit to larger funded teams to build a 410+ is pointless (HP wise) the 427 is a long shot, Knox is still hard on motors, regardless , Hell,IMO let the well funded teams run a "open small block" class I think it would be fun to watch, in the mean time, Organizetions need to open options to get some footing under them, if the direction seems pracical over time maybe a uniform engine rule would stick? ,im sorry but WoO should follow suit on this one , but, this is racing, nothing stays the same, ASCS didnt stay affordable, what one gives another takes, before ya know it , were in a mess again. owell, I still love 410's & 360's at full song.

Here's my idea make the track a small 3/8 mile and run whatever 410 you want old, new. Half mile sprintcar racing is boring to someone new to sprintcars, I think this would make it cheaper to be competetive and put new fans in the stands. JMO

The dollar figure I heard tossed around was $10,000 to $12,000 for a motor with a lot less frequent freshening needed...

who wants to eat cheerios every morning? good point on new fans though, the shorter bullrings are full of action and theres usually never a dull moment to a newbie, this is usually a feast for the eyes , for us that have been around a while a 410 running TQ on a half mile is music to my ears!
