Discuss: It's Time For 360's in St. Louis

Okay… thanks Howard.

So that begs the question for me, why the two classes (360 or 410) at all?

If I were to look at getting in to a sprinter and was putting together a Chevy power plant under open rules with only a cubic inch restriction. What’s the engine bill difference between say putting together a 355 or a 406? If I can buy all aluminum castings for both…. Stuff ‘em with titanium and ultra-light weight forged steel stuff for either one… and I can have the machinist do everything that has ever been thought of to make them produce more power, last longer and weigh less to both. What’s the $$$ difference on the final engine bill? Few hundred more for the 406?

Now the STOCK steel block on the 305’s would be a pretty significant cost savings…. And so would a steel-block if a track or sanctioning body was putting that restriction on the 360’s… But I’m not really seeing the reasoning for even having the two classes. Unless I’m missing something, which could always be the case with me. :eek: LOL
 
You can put as much money into a 360 as you can a 410. The 360's dont get to run aluminum blocks. If you run ASCS tour, your only allowed to do a little bit of head work.
 
360's were originally a concept to produce a sprint car class that were very similar to open(410's) except with a smaller price tag... That gap has significantly narrowed since the inception of the 360 classes. And those steel blocks don't help too much with the lower prices either, 360 or 305.

Closest thing I've seen to budget billing in sprint cars is the 5.3 liter class. They use the Chevy 5.3 liter(as it comes in a Silverado), the factory computer and all. Basically a crate class with a low buck, good performing, reliable engine. Pretty equivalent to a 305, minus a few grand under the hood...:)

If you run ASCS tour, your only allowed to do a little bit of head work according to the rules; however, the ASCS does little, if any, teching of engines because they do not want to lose their top drivers.

Fixed it for you Jeremy.
 
"Split the difference and have 385's."

Actually that is pretty close to what many of the ASCS engines have. :)
A stroked 350 small block has 383 cubic inches.

Okay open-wheel people, help a stockcar guy understand something, please... Is the ONLY rules differences between a 360 and 410 sprint the cubic inch limit?

its no different then say the A-mod and B-mods..Most b-mods can bolt a 4bbl on and run pro mod no problem as alot of them carbs are the only difference..360's sprinters have to run a steel block,they can run the ascs spec head or any other 23 degree head and use the ascs stamped gaskets which cannot be trimmed or altered..the 305 classes are getting to where they cost as much as a good 360 because they are allowing aluminum heads,injection,ect..This is racing,doesnt matter to be competative in any class you better be ready to spend some money.there are 4 bangers out their with thousands of dollars in them to race for trophys.it is the nature of the beast and isnt going to change,been that away for years!

we still spend less running our 360 sprinter then we did running our door slammers weekly!
