Funny thing about those 99-04 2 valve gt's....they pretty much suck with just boltons and gears, but once you do a good set of cams they wake up pretty nice for what they are. I traded a 04 gt with full bolt ons, cams, gears, and tune for this Camaro, and while they're is no comparison obviously they do okay when cammed

Not siding with anybody, but why in the hell WOULDN'T you use your car's advantages during a race?

If he has to put on a slick and dump it at 6500rpms, so be it! That is his advantage!

There is a reason 500whp Honda guys on stock suspension and shitty street tires don't usually run from a dig and prefer a roll

I thought 2v = crap no matter what. But with a set of cams they can run. Mrbigjeep's car showed me that. It actually opened up my eyes on 2v's.

I've done told you why. So you know how your runs in real street trim.
Who cares? If he beat me by 2 space ship lengths I'd shake his hand same as I would if I beat him.

I agree to a certain point. But a 6500rpm clutch dump on slicks.......How much does that car slow down on a normal tire.

Do they even break 12's with cams?...lol

The 99-04 2 valve gt's can break high 12's with cams for sure. Shoot mine with full weight and a crappy 2.0 60ft did a 13.1. Get the 60ft. down to a solid 1.7-1.8 and it has a 12.9 easy

I dont agree with this at all? Just because your stock cammed ls6 didnt like them doesnt mean a cammed car wouldnt considering the power delivery is going to be drastically different and shifted further in the cammed cars case.

Case in point; My brothers X4 cammed SS had 4.10s, shifted around 7k and was an absolute monster for what it was, trapping 121mph full weight in 3800ish+ DA

I'm sure some cars would like them.....some of those cars might like 3.90's or 73's better. Did your brother try other gears?

I answered the guy in the this thread. Did you see his cam specs in his sig? Do you think it's peaky?

Hell there are alot of guys running 4.10's with bolt-on's....bad choice imo.

I am assuming we are talking stock height tires here.

The one turbo 2V guy in this section did that for me.

So shocked to see them run well!

It seems there are a bunch of 2Vs in my area but all of those with 4Vs have seemed to sell them off to out of state buyers so there aren't many around anymore besides a few for sale at local dealerships

Wait, wut, now it's not cool to launch your car at 6500 rpms on slicks?


Guess I'm still in with the cool kids, since this was only at 5000 rpms

i may try 3:73's in mine. it already has 3:42's but it will make a little difference. it's not like gears are expensive or hard to change if I want to try something else.

3.73's are a great gear for a bolt-on car. The rears are'nt strong enough to utilize much more gear any way. Notches mild bolt-on car went over 116 with 3.73.....still don't have headers on it.

to utilize a different gear requires different changes. like different size tires or cam and headers.


I still don't have headers on my car. my best speed has been 112 mph in awesome air. typically 109-110 in the summer heat.

i agree with the 410s. i think they require too much shifting. i don't see how a bigger could possibly make less power 5500+ over an ls6 cam. i think the bigger cam wanting a steeper gear is null. if anything i think the ls6 cam would like less of a gear given the linear powerband.

Not really. You need tire to utilize it. More gear better for low end power less gear better for top end. More power should equal less gear given the same rpm range and weight because it should accelerate the car to a faster speed. If someone puts a peaky cam it their car than maybe they could use the gear, but most don't turn cam only engines as hard as I do. I turn my ls6 7000. It not hard to get these cars to go 115-118mph in the qtr. At 6000 rpm in 4th gear works out to be 112 according to f-bodygears.org. Now @ 6000 rpm a bolt-on ls1 is 600 rpm past peak hp. You have not even got to a good trap speed for these cars yet. Over geared at that point.....by quite a bit.

Your right on. problem is alot of crappy set-ups out there. They shove a cam in w/o full bolt-ons then it runs crappy and they try to use the gear to make up for it. Everything ends up not working well and this is why you see cam only cars in the 12's and even some h/c cars.

I think 3.73's would not hurt my car at all. I'm already past peak power with the 3.90's goin threw the traps at almost 6700. I'm in 4th gear in a little over 7sec.....1st gear feel's like it's almost not there.

i told Notch when he wanted gears for his car 3.90's was probably a little better for drag racing, 3.73 was gonna be a little better for street racing.

Besides 4.10's are weak compared t the other gears.

I always thought gears should match your Power/RPM range, and MPH per gear.

Obviously stock gears on a cam that makes power to 7k+ is going to just hurt you because you will be going x more MPH in each gear, technically just making your gears longer.

Atleast thats what works with hondas and id guess general automotive ****. 4.10s on a stock cam car with stock redline is only taking away MPH for every gear your in, thus hurting more than helping, IMO.

Basically to sum it up, gear compensates for the extra RPM.

Which is why 4vs that spin high benefit so much from gears, cause like hio said its a way to patch up there lack of broad power. But it does work.

Going from 3.23s to 3.73s sent me from 110/111mph to 114 mph. Then I did milled heads, tiny cam, and a 2800 stall along with going back to a 3.42. Now I only trap 115-116. Car feels like it drops too far out of the RPM going from 2nd to 3rd and isn't at an optimal RPM crossing the line. So yea, the key is to match your gear to your combo and cross as close to peak power as possible.
