Hey Everyone,

Just thought I would share this with everyone. Hopefully, we can get a LS3 into asphalt sprint car racing.

Wow, I am impressed. 13-15K with a rad and accessories!!! Shit, guys in the norheast are paying 20-22K for an f'ing 2brl sportsman small block that has to be rebuilt every year and doesn't include ignition, exhaust, or carb.

Congrats on the development. I hope they get behind the idea.

Thanks,
You should show the video to your track officials. Could be running the Camaro engine in your cirlce track car on the weekends!!!

NASCAR Camping world series cars run a LS series Spec engine and has worked out pretty decent.... for what it is..... good thing about them is the 75-100 pounds of nose weight you take out of the car when switching from a 18 deg to LS....The (NASCAR) tryed the Spec motor in a Craftsman truck at Texas last year and the thing didnt last.... the package wasnt able to run the constant RPM.... that you see at tracks like Texas Atlanta.... California.... and it as well as its oil pan was short lived...

All you would have to do is show up with the check for their kick-back and they would be happy to help. NE Modified(and Sportsman) racing is all based around with DIRT does, which is basically selling out the drivers and rules to turn a buck.

We have one track that is honest about tech around here and they don't really seem to be into the crate motor thing. They have one class with crate motors and treat them more like unwanted step children than a feeder class for the faster cars.

Crate motors are some of the most cheated up pieces out there....

[NJSPDER]

Oh god yes. There was a point in the middle of the season where 4 winners in a row got bounced for the most idiotic and obvious cheating you can imagine. It is a crate motor that is supposed to be sealed, 2 got caught with cams, one guy was running a friggin 800 carb(you are allowed out of the box 650 or 750 depending which track you are at), and another nit wit shimmed the valve springs AND cheated the rev box at the same time.

Amazes me the lengths that people will go to for $500 and a trophy, they all spent several times that and ended up with nothing.

I like simple rules packages. Max carb flow, max primary size header with no steps and only 4into1 collectors with a max size, max cubes, max lift, and max compression. If you wanna get fancy, max intake port volume on the heads.

Let it read like this:
Max Displacement: 360 cubic inches
Max Carb: 650cfm (+/- 1%)
Max Cam Lift: .550 at the valve
Max Compression: 11:1
Max Header Primary: 1 3/4in OD no steps
Max Header Collector: 3in OD, No Tri-Y collectors, 4into1 only
The Fancy Head Rule: 200cc Max Intake Port Volume
Fancy Intake Rule: Cast Commercially Available Intakes Only
Fancy Bottom End Rule: Steel Rods Only, No Al or Ti

Make all of it as measured and absolute. Plenty of wiggle room for those who want to be fancy, but limited benefit to those who spend tons and tons of extra money. Simple rules increase participation, encourage sponsorship, and decrease costs. Low compression and low lift also lets engines live, which cuts costs way the hell down.

Why does it have to have a carb on it?
Now, to the sealed part. Although we do have sealed engines, we are going down a different path now. All we really want to see is the Gen 3 and 4 small block chevy's in cirlce track racing. Whether that be with a carb or not. We have packages for both. We are getting ready for a prompoters workshop and all we ant to do is get the engine package in the rule books.

We have an upbuild package for $2300 that you could put on a 5.3L and compete in any 2bbl class. The 6.0L could race in most of the 4bbl classes.

I think what happened with the GM crate engine has scared racing because of the cheating. But, that will never be controlled. How many other spec type engines do you know of that are 100% legal? Not very many. Now, what the crate engine has done is made it easier to police the engines because you know when something isn't right.

Anywho, I could go on with this forever.

If we took carbs off the motors around here there would be a huge uproar. They even have rules at some tracks and in some series against things as simple as 4-7 swap firing orders as a "technological advantage"

No LS block is legal for anything circle track around here. They are just caught in the past and holding on for dear life.
