I want to take a moment to thank and to congratulate Joe McEwen on a fabulous representation of the 602 crate engine concept from Pace Performance.

We could not have picked a better group to present this concept to the sprint car world stated Chuck Fitch (manager of Pace) , along with Joe came his family and his friends who all work together as a team.

Along with being a very patient and talented driver Joe helps many young and less experienced racers shorten their learning curve with set up and driving tips---Joe is truly an ambassador of the sport!

The 602 sprint package started as a vision and took the Pace Performance team many hard hours and dollars to develop the package to work in the sprint car application.

But after an end product was ready we needed to race test it and that is where Joe and his devoted team came in.

Things were a little rough at the beginning with the lower powered engine and the drivabilty difference between fuel injection and a carburetor but the McEwen team held in there and we ended up with an economical option to 305 sprint car racing that is proven to be reliable and competitive.

The 44 car maintained solid top 10 finishes the last half of the season and finished things off with a 4th place finish on Friday and a 3rd place finish Saturday at the season ending Little Guy Nationals

We have to also thank Bill Altman, Frank Benic and the entire Mercer Raceway field of Outlaw Sprint Warriors for allowing this engine package to first be developed during their racing venue and then finally welcoming the concept and package into full competition.

The 602 GM crate engine has been approved for competition with Outlaw Sprint Warriors for 2015 and there are other sanctioning bodies with interest in the concept.

We have also rolled the program into the 360 world using the more powerful 604 engine.

Look for numerous press releases in the future about the program and concept.

we have been running 604 sprints in oregon/washington for a couple years now they are great

are you driving your fuel and PS pump from the rear of the camshaft like traditional sprint application?
we have engineered and built a device to drill and tap the camshaft in the engine without removal---the finished product has less than 1/2 thou run out which is better than most machine operations with the camshaft removed.

It also helps to cut the cost of the operation but the bigest benefit is we do NOT break any GM seals

also---I have to ask what you use for a drive hub?
we could not find anything acceptable to us in the aftermarket world so we looked to our friends at Crate Innovations and had them engineer and build a proto type and then we had hubs manufactured once the finished product was tested.

good to hear we are not alone on this island and that the concept has been accepted in your area

Brad, can you post spec's and info on this motor. Were there any changes at all to the 602 package, ie. timing curve? to run methanol. I know that the 602's that run Oshweken use a different oil pan and timing chain and run a 750 carb. Can an existing crate be used or does a new have to be purchased. I am asking this cause a frind and I are interested in possibly putting a car together to run Accord Speedway and he already has 2 Hunts sealed crates.

It is worth noting that there are a few specifications parts, of course the motor is a ... initial estimated costs as a cost-effective basic dash car motor package

I know the oil pan has to be changed on the 602 and a battery box welded in, since it utilizes HEI ignition and an alternator. I think price wise you get pretty close to a 604 when your all said and done, at least on Pace website it appeared that way.

sorry for missing the comments on this board.

this concept has been overwhelming to us with all the crate venues we already had going.
the crate sprint program grew at an alarming rate within our organization so Pace Performance brought the lead design engineer (Don Blackshear) into a full time position, where he attends to this project on a full time basis.

Race-1 remains associated with the program and continues to develop and outfit this program as well.

I see a couple comments about the oil pan----------
we learned early on that the 602 8" oil pan was a problem in conventional sprint car chassis
In most all sanctions and tracks involved now----a pan swap is permitted
we use the GM 604 oil pan as a standard replacement (pick up tube must also be changed)
(still retains 602 std volume pump)

the charge at Race-1 is $400 to do the pan swap including our accepted seal.

the 602 has turned out to be an amazing engine for this program and all questions of how it will hold up with a methanol fuel and direct drive have been put to rest.

our current price on a 602 pan swapped engine is $3750
if you would want the cam spud installed add $550
if you would want us to do the new engine prep that is additional
if would want us to break-in the engine on our dyno that is additional

I think possibly the end price at Pace gets confused with the base price of a 604
as we all know, it's all the add on components and services that make the end price escalate.

we will be adding more sprint info on the race-1 website soon

thanks for the interest and I will try to pay closer attention to this board but please feel free to call or email me at anytime with questions or thoughts

when I break it down into individual pricing I come up with $7500
However-----
I "think" they have added a fuel pressure regulator and plumbing to the package (that I didn't figure)
also I "believe" they have upgraded the water pump and pulley system since the original build (which is more $)
in the picture and what I figured is a basic aluminum pump and pulleys---the upgrade would be about double in money

also recently the base engine price has come down $200 and I don't think the advertised price is reflecting that just yet

Keep in mind this is a Ready to Run package and includes all the components. (except fuel pump)

with this package a battery would be required -----we now have packages where a alternator is used and a very small lightweight battery is attached to the engine only to excite the alternator
the alternator package and self contained battery option is obviously an upgrade and has additional cost

interested competitors can contact me or Don Blackshear for more information

Why did they go Hei? Magneto would've eliminated the need for the alternator...

I agree and some individual tracks do permit a mag.----the first thoughts were that the cast camshaft would not work well with the added load of a magneto and we really don't have enough information yet to substantiate that either way. but there have been a fair amount of magneto fired engines in use and not any failures to speak of unless they use the wrong gear of course.

the biggest factor in the original conception was cost

the engine comes with an HEI distributor that although it is not my favorite piece, it has proved to be reliable and perform adequately.

the battery is a bit of a PIA but its been working out so far

we do look at ways to make that easier but unfortunately it also makes it more expensive

in the end a mag maybe more economical and at some point

Cool. I've been researching this across the country the last few months, at least as far as wingless sprints. You've got the:

1. NEWS GM602 wingless at Accord & New Egypt Speedways(602 w/604 pan, carb, trans, alt., battery, starter)
2. Wilmot speedway has GM604 cars , I believe with magnetos and 750 carb.
3. Elite wingless in Texas uses the Racesaver 305 w/injection and magnetos.
4. UMSS "Traditonal sprints" in Wisconsin are using the Pace Performance CT525 w/carb.
5. 360 SPEC Sprint class in California, but its having some issues at present.
6. Australia they have a non-wing sprint class that uses a GM3800 V6!!! This is the most popular class in the entire country along with legend cars.

So there are several different approaches to economy wingless sprint cars growing in our country and abroad, this is exciting. The most powerful and lightest of the, "Crate" variety is the CT525 with the UMSS series. The action and raciest is a toss up between UMSS and Elite 305's, followed by the GM604's and then the NEWS/GM602's. At first I was really into the 602 deal, it has a transmission, starter and was very simple which appealed to me, being from a DLM background. However the price of the transmission kinda dulled my enthusiasm for the 602 setup, that and its may be a tad under powered as they've had to raise the rpm limit this year because of issues with the cars not developing enough torque to keep the RR from digging in, so...

I've made some friends over the web who've raced sprints for many years and a trans may not be necessary, a friend told me that using a starter/flexplate was sufficient to get the car moving and to start it if need be. I'll go ahead and say I'm not a crate fan per se, at least not as mandatory. To me crates never would have become popular if the rule makers/tech men/sanctions had done an honest job policing and enforcing rules w/o favoritism. I'm looking at starting a class here in the SE that will be inclusive instead of exclusive, a class that blends crates and built engines, carbs and fuel injection. Some aren't comfortable building their own engine, so they can run crates, GM602/603/604, The MOPAR 360 crate, The Ford Crates. Some may want to build so bring on the racesaver 305's and perhaps even some stock block/head LS 5.3/6.0's. My point is there is room to have options without forcing you to choose one brand.

here is a link to the home page of the new RUSH wingless sprint car program that will be running in the NE part of the country in 2018
this is a 602 only and is well thought out and organized properly
it includes a shock and tire rule

Thank you. Too bad these type cars aren't more popular down south, I'd love to run one, but I'm in GA on the SC border(DLM country)

Don't need an alternator. Can run all night (in fact more than one night easily) without charging the battery. Dirt modified (IMCA, UMP, etc.) do it and they have to start the engine with a starter several times in a race night. Small light weight batteries available from Performance Distributors that work perfect in this application.
