I guess no one can debate what you've seen personally. I'm sure you're
aware how stout a cam only fbody can be in the right hands with the
right setup. We have cam only guys here in the 9's. There is no pulley'd
Cobra that can run that. It's flat out impossible. Pulley'd Cobras are
good for anywhere from 10.70's to 12.20's with the 10.70 end being
race car setups damn near and the 12.20 end being morons. It's far
more common to have 10 second cam only LS1. I'd say it's almost common.

You guys are all still failing to recognize the fact that both pullied Cobras and cammed LS1 Fbodies can be setup completely differently one to the next and have drivers at completely different skill levels.
You are also throwing all of these trap numbers around like once you run a certain trap on a specific day at a specific track, that's the number you can use to compare to anyone else's car with a certain trap at a different track on a different day. Or you throw around the BEST trap a certain car/driver combo has ever hit and use that as the factor, ignoring the fact that they might have trapped one or two or more mph (or more) slower than that previously that day, that season, and on the setup.
EXAMPLE: I'm an extremely consistent driver, especially when I had the Camaro. I went to LVD on an 85 degree day and trapped 116-117 all day. Then I went to Atco with the same exact setup on a 45 degree day and trapped 121 all day.
With this argument you guys have going, there are different pulley sizes, different brands for exhaust parts, different cam sizes, different weight reduction (or lack thereof), different drivers, different drivetrain setups, different gearing, different weather conditions, different tracks and prep at different elevations, cars and blowers at different temperatures from previous runs, different tire sizes to affect gearing, different transmissions, etc, etc, etc.
THERE ARE WAY TOO MANY VARIABLES TO EVEN SAY THERE IS SUCH A THING AS "AN AVERAGE CAMMED LS1" OR "AN AVERAGE PULLIED COBRA", regardless of any person's "previous experience". BOTTOM LINE.
How do you guys not get this? You're proving yourselves all wrong in this argument by stating anything else and posting up all of these conflicting examples of how these Cobras beat these LS1s, and then the next person posts up proof or personal experiences showing just the opposite.
There is no "typically this happens in the entire world" when it comes to two cars that can vary this much from one to the next and have this many variables from one run to the next.

I ran 12.20s with bolt-ons, Yank 3600, and 3.23 gears on 17s. Most of the bolt on only cars in my area are in that et range. Most of the cam-only cars are in the 11.40-11.90 range depending on cam size and weight. I ran a best of 11.64 cam only at 3600lbs with a 228R cam. Not saying your car is slow just stating the times that I regulary see out of these cars.
I only stated gears because generally that (and or a stall) is needed.

Good race OP!
As far as the rest of this mess, I think that a properly modded "pullied" Cobra (meaning that it has the supporting mods, not just a pulley and cold air, or something) will beat a "cam only" LS1 fbody more often than not. It can go either way depending on the specific setup, driving, etc. (as it has been stated numerous times), but the power difference between the two cars will more than make up for the weight difference (not to mention the torque difference) in most scenerios.

idk why your car has an MS3 and you say your happy with low 12's you need to stay and read up... lol kidding bro I know all cars run different but with an MS3/ bolt ons / proper dyno tune you should be well into the 11's if you can drive

This run was with 2.80 pully, k&N filter.....not the whole tube, o/r x, flowmaster/Borla hybrid catback, spec stage 2 clutch and nitto dr's. It was tuned by Stang Hi in Baton Rouge. It should have gone 11.50-11.60 but was only cutting 1.7x 60' due to very used tires. http://www.youtube.com/watch?v=QAOtldqCvPE
This one is a stock tire catback only car. Pretty much stock with a amature driver. He also cut a very shitty 2.126 60'http://www.youtube.com/watch?v=HPwwdGLqlrk
Like someone said....too many differentials.

like I have said many times. cam only ls1 dont get close to the 11s here. and my car wont see a track so I am not worried about. it does VERY well on the street. thats what I built it for......

I don't go to the track. been there one time. its not fun for me. I have a stock 10 bolt with 342s. if I built it for the track gears and rear end would have been my first mod..... drag radials are street legal. track would be slicks. I can drive my car anywhere I want with the a/c on. I don't want a race car.

Well I'm not cam only but I have a small 226 cam and hand ported heads.. Stock intake... He could come run me. ![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
I have raced 3 other Ms4 cars and beat them all... Pretty good I might add. Should I have? No, they were all setup poorly and I know that. So yes, all 4 of his very well could have been. He definitely has a strong running car for a stock Eaton but a good running Ls1 will be right there with him.
I know how your car runs!

i have never seen a 120+ cam only car and my pullied set up went 123-124 consistantly without icing down anything. my car actually never failed to trap lower than 121 on a clean hit when it was pulley only. i will say that i have only seen 1 or 2 other pulley only cobras go in the low 120's.
