Flycutting and rod bolts give folks advantages, at that point you could run even bigger cams and spin the engine even higher... Once you do either "cam only" does not mean a whole lot I think.
I think we always have to give props to those brave souls who are spinning stock bottom ends to 7K and run low 10's and high 9's.

This reminds me of all the Fastest stock short block Turbo BS.
Cam Only rules are dictated by the car who holds the record. Congrats on the dedication to push the envelope and the Results.
As for Rod Bolts and Fly Cuts, Its still cam only. Hell if it was Cam Only it wouldnt have bolt on's... See where this goes? It all mincing words

No Its Not. "CAM ONLY" Means "ONLY A CAM".
Everyone should call it Cam/Sprins/Intake/Throttle Body/Headers/Electric Water Pump/Ect, Ect....
We can Mince Words and Manipulate this all night. Then again it been done for years already so why waste the time?

Every Cam only car has Cam/Sprins/Intake/Throttle Body/Headers/Electric Water Pump and what not. now your just getting stupid about it. Fly cutting in my opinion is not cam only now your starting to internal modify the motor for performance advantages. have to draw a line on were it stops....

Yes Fly Cutting allows for bigger cams.
Yes Rod Bolts make higher RPM safer.
Does eighter make it anyless than "Cam Only" or does it just make it "BIGGER Cam Only" ?
Seems to me Fly Cutting to allow for a bigger CAM to fit in efforts for more performance is what Cam only is all about.

Since this is the case, maybe I should make a sticky with the designated "cam only rules" since this is basicially an ls1tech "class", so to speak....
You guys decide what you want to do, and I'll make a sticky for it.
IMO, the only thing that should be required for it is:
4th gen f body car, "stock" suspension... no back 1/2's etc.
whatever you want to do with the driveline do it, no clutchless tranny's like a liberty or the like.
Motor wise:
Stock crank, rods, pistons, stock casting heads not porting decking clean up's, valve jobs, etc. Stock, or drop in replacement lifters, no solid roller stuff. Other then that, do what you want as far as engine management, intake, flycutting, rod bolts, etc. NO dry sump oiling systems, you want to put an aftermarket pan on go ahead, your $. Oil pump, timing set, all that stuff go ahead replace it, you're in that far at that point anyway.
I'd be more strict about that.. but the problem is that these ls1 engines are getting older, and the liklyhood of finding a perfect one that's healthy enough to be up to the task, without needing a refresh (rings, bearings and whatnot) is probably getting slim, or at least harder.
Feel free to discuss it, and if the general consensus is one or another that's fine.
Come up with the definite "rules", and I'll make a sticky. This way anyone that wants to take a shot at it, at least knows what the limitations are. Not that there's an official board that goes around checking this stuff.. it's on the honor system for all intensive purposes.

I would think that since Chris and Charlie hold this internet record, using there car as a guideline would be a good start. Now when others are chasing this "Record", they will all know what it took to run the 9.98 and what deviations to there own cars they have, If any, in the attempt of claiming the title.

JL's guidelines look fine.
Get over the Fly Cutting. It is not a performance mod in it's self. If anything you are lowering compression. Diminishing performance
.
It does allow you to run a larger Cam. This increases performance. IE: "CAM ONLY".
Rebuttal?

The problem will be this. Someone fly cuts some pistons. Adds some rod bolts. Tosses in a custom donkey dick cam. Then proceeds to beat the standing record by a tenth or hundreth then the deal is done. Some will bitch over the fly cuts and rod bolts. Some will come out and respect the accomplishment. At the end of the day it is still a "Cam Only" car. It's just a more extreme version.
Racing is racing. Manipulating the unwritten or written rules is gonna happen.
