GARY2004Z06

Just got off the phone with Jason Miller. Since GM is not represented in this class, we thoroughly discussed how we can get cars involved. The new rules are to be out soon. (I'll keep everyone posted.) In a nut shell, we are getting a break with weight reduction. This is huge for all of us wishing to compete. The LS1 & LS6 cam only crowd will get the biggest break. The bolt-on only LS7 guys and gals will be 150 lbs. heavier. LS2 and LS3 cars will fall somewhere in between. Please let us know if you have any interest in running to put on a good show for the crowd and represent.
Who knows, maybe we will get to eat some rice.

2014 WCF Rules

Big weight reductions so we can finally compete.

Rob Petyo

Can you please explain this?

Does this mean I would be competing against someone (car & driver) about 2,700 pounds? I don't think my coupe would stand a chance.

Would my 382 fit in with the LS6 block?

LSOHOLIC

The way I read it is...its basically a cam only class with full bolt-ons. OEM heads unaltered...in anyway.

The rules will favor a purpose built machine, specifically for "their" rules.

The only mods allowed are; Internal engine modifications are prohibited except for aftermarket camshaft, hydraulic lifters,
valve train, and overbore (See chart below for max CID) .

So looking at the weights, it would pay to max out the cubes as well as your dynamic compression (overbore; aka, some big domed slugs with nice valve reliefs) and put the bit*h on E85. With a big nasty cam and try like hell to make the minimum weight...good luck. Unless its just a gutted racecar.

With the right combo I could see 500rwhp @ 2850 being somewhat competitive. But is obvious to me that the rules still favor the imports.
I've heard that is was a deliberate move because.....the imports are less reliable and have trouble going rounds.

But it would still be fun for sure !

IMO, this is a 10.2 -10.4 class for a IRS vette but the imports will be running 9.7 - 10'ohs.

Rob Petyo

Totally agree!

However, what does look like a LOT of fun to me is the 10.50 index import / domestic ...

If this old man can cut a decent light (going deep) on a .400 pro tree, I could only hope to qualify. Ran this at E-Town once and did pretty well.

Have to be careful with getting a flat when the inports are runninng, leaving junk all over the place. I stoped it because of the flat tires...

This might be fun

the wild rice is very sharp like tacks

C5 Pete

I don't believe deep staging is allowed.

I can put stock LS 7 heads on my car and weigh 3150.
I'm allowed a valve job.

I plan to swap cams and find some heads and run 9.70/80

LSOHOLIC

Thats very impressive Pete...what cube are you ??

I hope to see several of you NE guys compete in this race.

C5 Pete

I've got an LS7-427

LSOHOLIC

Lol....what am I missing Pete ??

And stock headed & stock cam LS7 will run a 9.7@3150lbs in average air in your car ??

Am I understanding you correctly ??

.

C5 Pete

At 3150 lbs I can run an aftermarket cam. Stock heads.

LSOHOLIC

Ok....what does this statement mean ?

LS7cars must run OEM camshaft and OEM valve train.

C5 Pete

Read the fine print my friend.
LS 7 with cam - add 150 lbs

LSOHOLIC

Yep....lol...there it is in black and white...lol.

Gunna need to loosen up the converter a little ??

Good luck....

C5 Pete

I broke my flex plate at LS Fest so I'm gonna replace it with an SFI one and I've got a new converter for it too - unrelated - I had already planned to swap the converter.

Now I just need to find someone with some stock heads and pick out the proper cam.
