Yeah those steeper, shallower, taller and shorter gear descriptions can get very confusing at times LOL. That's what I always simply follow it up with "numerically higher" or "numerically lower" to clarify what I mean.

I've always understood steeper to mean numerically larger gear.
Steeper = increased elevation grade, so it stands to reason an increase in numerical gearing.
He used the term properly as far as I can tell

But the problem might stem from "steeper" appearing similar to "taller" as both are 'higher up' so to speak. But the term 'taller gears' often refers to what they result in such as taller (higher) highway speeds meaning numerically lower (a 2.73 as opposed to a 3.42 for instance). 'Shorter gears' often refers to what they give which is quicker acceleration in short spurts or numerically higher gearing.I think.

Well I took my car to see what it made on the dyno the other day (monday) at a local shop..
First my mods are: longtubes, x-pipe, stock axle back, varram, slp underdrive and a ls7 clutch, cutouts... I do believe that is all..
My best was 430hp/415tq... Just thought I would share with the rest of you vette owners, I'll take a pic of the graph next time i run up to the shop... Numbers are uncorrected in 60 degree weather pretty much at sea level where i live on a good day.. I am very pleased to say the least..
BTW, it makes power all the way through 6500 rpm, I shift at 7000.. soon to be higher after a fast intake..
Oh, I also ran it at the track... With a bad master cylinder and not getting into 4th gear (letting out at 110, top of 3rd) letting out a considerable way before the traps...
1/4 E/T: 12.3
1/4 mph: 110
60' : 2.0
This pass was on a set of bridgestone potenza's with 18000 miles on them that have been sitting up for 10 months while my car didn't have an engine.. This resulted in immediate loss of traction after i left the prepped section of track and wheel hopping/spinning literally the entire way down the track...
I am EXTREMELY pleased to say the least..

After FAST intake with stock cam and you'll be shifting above 7000rpms, WTF! LOL LOL LMFAO
POP!Hmmm top of 3rd, 7000rpms, 110mph? Is that a Z51/MN12 combo?
BUT, look at it this way. It's a cam away from being a true 430rwhp 120mph car.

I'm sorry, but I couldn't resist. NO CAM + Stock LS2 intake shifting at 7k RPM shifts. WTF !

I would throw up if my cam+bolton ls2 made only 430whp...

Oh, you've pulled the valve covers and checked the spring's loads and rates and all of that?
Because that's really the ONLY way to know for sure if all is truly well with them.
Personally, I wouldn't repeatedly take a stock LS2 valve spring any higher than 6600rpm, especially if they have some miles/hard passes on them.
Are you familiar with the phrase valve float by any chance?

Without a Ported FAST that's about what you could expect with a moderately sized cam.
With the intake 450rwhp is typical for a moderately sized cam.
Like we've been saying, SAE corrected you can expect that your setup is about 40rwhp less than what your dyno showed.

And i am pretty sure the numbers are going to be considerably lower SAE, as ive said many times before.. I just posted what it made on a given day in near perfect conditions.. I thought that it was pretty impressive for a bolton ls2 car to make those kind of numbers. I thought some of you would appreciate it. uncorrected of course.. but it still made them all the same..

Lol. He installed ARP rod bolts, but left the stock valve springs and pushrods in and plans to spin it above 7000rpms after the FAST intake... lol.. OP, keep the funnies coming. No wonder why you have all that work done and trapping what a stock ls2 traps... you're wasting valuable ET and mph spinning to 7k with heads/cam/intake/pushrods/valvesprings and oil pump that doesn't support those rpms. Stop listening to your 2011 mustang 5.0 buddies. There is a reason why they are burning up the #8 piston after a tune by spinning it to 7500-7600 rpms instead of the OE spec 6800 rpms.

and i'm trapping what a stock ls2 traps? explain your logic please, if your stock ls2 trapped 110 then you have got some problems with your car or you are just a plain out terrible driver... my car ran a 12.3 with a 2.1 (maybe 2.0) 60' at 110 letting out way before the traps at not going into 4th.. You should come on down to south ms, see what this lil intake exhaust ls2 has got.. it only traps 110..

This whole thing is a joke, right? You're just having fun with us, right?
OP, I saw a lot of very experienced members trying to educate you but you keep getting wise without trying to learn. Keep posting though. Your true personality and intelligence is coming out.

lolwhut?? do you have even the slightest clue? The new 5.0's don't burn up because of rpm, they burn up because the number 8 cylinder is the leanest cylinder and doesn't register a/f like it should. tuners that tune on the limit instead of to the leanest cylinder tune the afr's on the limit and the number 8 cylinder goes way lean, hence the gigantic hole that appears in most of them..

This is a joke right?? LOL, "Way before", LOL
What was your 1/8 mi mph?
We're still waiting on that dyno......
It's only a matter of time before your engine goes. It's an LS2 not a Boss 302.
