If you had the same trans and tire size, this is relevant. This is not at all representative of a 1LE vs SS in stock configurations.

Great comparison with transmissions being the same!

Agree. If the point was, do gears matter, then absolutely!

I enjoy the gearing of my 1LE, seems to work well on the street. I know its not optimal for the 1/4 mile but oh well, it is what it is!

No one said it was and no one said it was a SS vs 1LE thing either. It’s just a video don’t read into it so much. Plus every car and engine are always different. You won’t get the same exact results from two cars with identical setups.

Yes, in the end gearing will always help a camaro cause its so damn heavy!

The only thing I read into the video, since there was not commentary given with it when posted, was that it was posted in relation to the context of the conversation preceding it - a logical conclusion in the absence of any other information or discussion put forth with it. Hence my response.

I agree - no two setups are truly identical, and thus will not yield identical results. And I would agree with what the video shows, the car with 3.91's easily pulls out on the car with 3.45's. Especially when you add a cam and further focus the power producing range to high RPMs, as both cars had in that example.

The 1LE trans certainly has an advantage in the gear spacing - the big gap from 3-4 in the SS trans is gross. The SS trans's only advantage, if you can call it that, is it's lower 1st-3rd, which when paired with a more aggressive gear, give it a drag-strip launch advantage.

Look at the cam specs; compare years; he has non electric power steering, loss of say 5 hp.... but he has a tighter LSA usually better for specs on dyno and better power top end compared to a wider torque of a wider LSA. He has more lift on his specs, the intake spec lift is high sucking more gas which out does the little added duration of you cams specs, while your cam has a longer duration for more exhaust scavenging and Sound..his cam does that with lift also a little higher. And any dyno can be different from another for power on a sheet.... I would say he actually should be at the same power level as you or maybe more, and yes to go 1/4 mile a 1le has to hit 4th due to gearing a SS not so much......making them actually slower for drags compared to the 3;45s the 1le made for tracking twisty turnies.

learned a lot in this thread!!

found out that the car actually has a cam motion stg 3 titan cam.

Grind # XA227/365-XA237/355-13+3.5
Duration at .050": 227/237
113 Lobe Center Angle with a 109.5 Intake Centerline
Lift with 1.7 Rocker Arm Ratio: .621"/.604"

Great cam, I was going to use that but decided on a Texas Speed 225/236 cam which is close. My cam is fantastic, would not change it. That BTR stage 4 cam kinda sucks if you ask me.

More like it's not suited for what most people want/are setup for. Cams like the BTR STG4/F-35/GPI SS3 are really more or less "Max effort without pulling heads" type of cams, and they definitely sacrifice under 4000rpm compared to something more bit mild like the Titan Stage 3. The flip side is that they pull so hard on the top. And it's not just that the peak number is higher, but they don't lay over - so you run them out to 7400, and shift right back into the meat of power.

Translation - great at the drag strip, or if you don't mind twisting a little more RPM to dig into the meat of things. I think cam's like those should have a 4.10 minimum when paired with an manual. They really benefit from a rod-mod intake as well, fatten's that mid range up and really extends the top. Putting something like one of those into a car with stock gears is leaving a bunch on the table IMO.

It's definitely not for everybody, I would think most people would rather give up a few tenths to have a stronger mid range and better manners.

If I could change one single thing in my car, it would be this. It's difficult to keep the engine in boost during the 3-4 shift.

Wow you guys made great power on those cams, my full bolt on 2010 Ls3 with TSP stage 3 made 453whp and 414wtq...I was dissapointed, my tuner is also one of the best in the area.

Dyno number just don't mean much. I found 24whp just by dynoing on a different dyno, exact same setup. https://www.camaro5.com/forums/showthread.php?t=534338
