602 sprint car
 

Saw a video on Facebook from plymouth speedway, James McFadden was running a winged 602 crate engine sprint car today. Supposedly running them every week at plymouth. I'm not trying to start a bashing thread, just thought that was interesting. First Bloomington bringing the 305's and now a different "economy" sprint car class. Read somewhere that it costs $6995 for engine, complete ready to bolt in and go. Kinda interesting

Re: 602 sprint car
 

This car has been in the works for close to two years. we have been working with Pace Performance, Race-1 and Blackshear Racing Engines in eastern Ohio. A 602 engine car ran last season at Mercer Raceway with their local 305 cars and was competitive.
With a commitment from Plymouth Speedway to run them beginning in 2016 and my relocating to Indy our focus has been in Indiana in conjunction with Rich Farmer, Joe Gaerte and advice from several experienced sprint car people.
Rules are mostly complete pending tire testing.
There will be a public announcement in the next couple of weeks and rules will be available shortly after that.
In the meantime you can contact me at 317-416-6854 or larrykemp1959@yahoo.com with any questions.

If someone wants to provide me one of these engines i will take out my 12 degree 410 and run it a few weeks at Putnamville and Paragon to see how it stacks up to regular non wing cars. If it proves it can make the show and run competitive at those venues it could be just what the Dr ordered to grow participation. Message me if your interested.

Re: 602 sprint car
 

We are in the process of collecting parts to build a 602 sprint, 2015 spike. I talked with Don Blackshear about this after reading a post in hoseheads forum and was interested. we are on the west coast in Ca. and like to see a non wing affordable class other then a 305 and keep it affordable. we are waiting for the rules and tire selection, our plans is to complete this car and possibly ship car back in time for 2016.

Re: 602 sprint car
 

I would support this as a viable alternative to run WITH the 305's. The previous post about running one against the 410's isn't where this motor is intended. It will never be competitive, just as a 305 isn't against 410s. It sounds like a great idea to get cars that are sitting because of engine costs to the track in a support class.

Re: 602 sprint car
 

Until the guy in the 602 wants a 604. :31:

On the right track with the right conditions a 305 beat the 410s at the boss race at Fremont. A true upset.

Re: 602 sprint car
 

Getting close. Hope to have an announcement and rules by mid August.

Gotta be carefull when you are talking about Ohio 305's as majority of those guys are running bigger motors due to the fact there is zero teching at Attica or Fremont.

Re: 602 sprint car
 

Maybe I'm missing something here, and don't let this sound like I'm critical of anyone trying something new, but it doesn't seem to make a lot of sense to take an already under powered car and put a wing on it to make it even more under powered.

Why doesn't anyone give the CT525 a shot? They are rated at 525 hp with 471 ft/lbs. of torque and cost $7200~.

We are currently taking engine donations. :6:

Re: 602 sprint car
 

wilmot in WI has a 604 non wing class. It puts on a good show for the first year of it.

Re: 602 sprint car
 

Just looked at Wilmot raceways web site, 604 non wing class and read the rules. they seem to have a good program and affordable. Hope they can increase car count to 20 to 25. great for fans on 3/8 mile. I checked drivers standings/points seems to be 10 cars currently, also watched a video.

Re: 602 sprint car
 

Without wings you can take any 305 rules package motor, one of 5 different crate motors, a sealed shwanke 5.3L EFI motor, a 2 barrel 360 motor, and have good competitive racing with nobody being at a real advantage or disadvantage.

When you take a car with shocks and tires designed for 800-900HP and add a wing designed for cars with 900HP you have to start making sure all the motors are dang near identical. A little extra power really shows up in a class of vehicles where everybody is so under powered to begin with.

Until they invent and implement a wing that is purely decorative that has little or no downforce or rudder affect any winged econo sprint class will have to be running on one standard engine package. And the crate motors still allow massive dollars to bump up the HP. Lots of the crate latemodel guys sell used engines for double the price of a brand new one because they have gone to a certified rebuilder/sealer and gotten every bit of tolerance and balance pushed to the max. And soon somebody will invent a crate sprint specific intake package that will kick the crap out of a 750 holley or an old hilborn injector and guys without it will pretty much be forced to buy it.

But going back to my first comment... get rid of all the downforce and rudder and you can combine 20 different econo sprint engine packages and have great racing.

Wouldn't it be better to try to cheapen the 410's somehow? Get rid of the expensive shocks and run harder tires. I hate to see things get divided up like go karts. A whole bunch of classes with not that many in each.

Re: 602 sprint car
 

From what i am hearing this should be a great entry level sprint class. I have been at Plymouth for years and have saw the Outlaw late models go from 30 cars weekly to 12. 410,360 will always be the biggest and baddest. and i know that you can find cheap 410 motors out there but not everyone can find the deals on them like some that are lucky to find the deals. But anyone can go and get the complete motor brand new with new carb, headers, and ignition. ready to plumb and wire in you chassis for $6995 and run 2-3 years with no rebuild. Sounds like a great hobby class. I like non wing cars but with the World Racing Group (World Of Outlaws) putting this program together is see why the wings and safety. Also I am hoping to see a lot of rookies in this class or the drivers that have retired at don't want to hustle the 410 cars like they did back in the day. JMO

Re: 602 sprint car
 

Take the time to Google Ohsweken speedway, and their crate program. The cars do run fairly well, and by A-main time the crates are about as fast as a tenth place 360 most nights.

Re: 602 sprint car
 

I really hope this class works weekly. To think a new engine and parts with everything ready to bolt in and go for $7000. Where can you get a new 410, 360 or 305 for that. Hear that Joe Swanson already has one along with a few others. I when you hear guys like Terry Shephard looking at it that great for the sport.

Re: 602 sprint car
 

I wish them luck, but in my opinion I don't think the sport needs more divisions. We have wings, 410, 360, dirt, pavement. Sprint car racing is a small pie, and I don't know if it is good to slice out another piece.

I hate to argue mr funk but in my opinion there is a lot of sprint cars on stands because of engine cost. JMO

Re: 602 sprint car
 

WE agree, to many cars just sitting. go to the track and watch sprints combined with modifieds or micros, not fun. out hear we have a senior class that could be replaced with a good spec program.

Re: 602 sprint car
 

Have the rules become available, 602 crate sprint car ?

Re: 602 sprint car
 

Final tire and shock tests next Tuesday, weather permitting.
Trying to find current production tires with wear and performance history that will work well with this program and at an affordable price.
Won't be long now. We just want to have the right program when announced.

Re: 602 sprint car
 

Wing or non wing ??????????????????????????????????

Re: 602 sprint car
 

We have been testing with the wing as that is the way they will run weekly at Plymouth next year.
The rules allow either and there may be some Non winged events as the car count grows.
Test went great last night. Thanks to Randy Hannigan and Joe Gearte for helping with the set up and shaking the car down.
Rules should be forthcoming from the sanctioning body.

Re: 602 sprint car
 

In the mid nineties in western PA we had a limited 360 division with a right rear spec tire. There were probably 25 cars in the immediate area. One track was closing but another was opening. They said they hadn't decided on the rules. When they did decide, they decided to go with a set of rules for which there were no cars in the area. Tough choice. 25 cars ready to go versus 0 to go. Needless to say, it was our Gold Crown moment. Deja vu. :41:: And then as if that wasn't bad enough, we had our second Gold Crown moment. Needless to say, it didn't work either. But then we were graced with our third Gold Crown moment. We're still in that but looking for our fourth Gold Crown moment. Just call us WPAC.

Under cover porting, look alike 602 heads.

Re: 602 sprint car
 

check out northeast wingless sprints they race at New Egypt Speedway there is videos on youtube and they are on facebook, its a 602 crate wingless division...... they are a brand new division this season and seem to run ok , but seem under powered on the 1/4 mile bullrings. They have racced at Accord Speedway which is a high banked quarter mile tight corners and they don't have enough power to rotate the car on its big tires and push like dump trucks.... affordable but a little boring to watch

Re: 602 sprint car
 

That hasn't been a problem in our tests at Plymouth, Mercer, PA. or at Oshweken were they are finishing their second year with this car. A lot has to do with gearing to be able to use the high torque these engines have and to just touch the chip going into the corner. We are using slightly smaller tires on both sides in the rear which helps.

Re: 602 sprint car
 

Since this is an external balance motor what are you doing about balance?? Is someone taking these engines apart and rebalancing or have they came up with external bolt on weight??

Any update on the tires rules, ect?
Heard from one guy at Plymouth there are about 7 guys right now trying to build one and possibly many more on the way.

Re: 602 sprint car
 

What other tracks are using this engine?

Re: 602 sprint car
 

Blackshear Racing engines developed a balancer hub just for the 602 engine as well as created a fixture to drill and tap the back of the camshaft for rear mounted fuel and power steering pumps. they also engineered a combination carb spacer plate/throttle linkage piece.
