I dont know how knowledgeable the officials are about LS style heads, but it one were to comepete in a cam-only class with non stock castings, I'm sure someone might say something to somebody.

There's index racing and bracket racing - run anything races.

No need to try to cheat the system to get into a heads-up race...

studderin

iTrader: (28)

hows that cheating, it's the class rules. i'm sure the other brands are the same way,

ATVracr

Unported 243's should be fine.

Jason Miller has specific guys teching the LS cars that know these cars pretty good.
If there is something they have a question with me or Steve will be there also.

studderin

iTrader: (28)

26x11.5 slick and any size drag radials except 315/60/15, 325/50/15, 295/55/15 and 295/60/15 ..... Studderin are you coming down? It would be cool to get as many as possible cam only ls cars to run.

studderin

iTrader: (28)

ya i would like to go, get some ls1 cars to do good.

26'' slicks
wayne most run 28'' 275 drs,
for a t56 car, that sucks. i really wish it was 28x10.5 like everyone runs with a 6speed.

I certainly didn't intend to infer that anyone was trying to cheat... I appoligize if I offended anyone.

And after re-reading the rules it seems they specify blocks and specify head castings, but they dont say which heads on which blocks.

So I would agree, a cam only car can run any heads (casting numbers listed) as long as they are not ported....

Best of success to everyone going down...

It's going to be a great event.

So what classes could I race in with the ls1 rx7?

Might be a good end of season event. I dont know many 11.50 import bracket cars but then again this event looks a lot bigger than anything local.

Is the prize money given out to the import and domestic winner of each class or is it the overall winner domestic and import cause if its the latter I cant see any imports really winning any money.

If payout is to each winner on the domestic and import side I might go for the 11.50 class again.

Stock intake manifold?
Sounds like factory shoot out would be your class.
Check your tires though. No skinnys and no bias ply.
