NOS or 4.10 gears
I got a 93 6 spd with a head/cam/ header package. What would be a better choice, going with a 100 shot of NOS, or getting 4.10 gears.
My biggest concern is, if I go with spray, will the stock bottom end hold up??

Took me 10 years and 50+ bottles. Throw in a few thousand dragstip runs too. If it does not run lean it will hold up very well. Fuel and ignition systems must be on par or better. Also greed kills. Very easy to bump a 150 shot to 250. $6 for jets and 3 minutes work. Avoid lean and greed and all will likely be fine. I had an injector stick open and wash down the cylinder wall. I hold the injector responsible for my failure.

Nos
The nitrous will give you the biggest gain for the $$$. The bottle can be turned on and off when needed, the 4.10 gears are permently using more gas and ALWAYS running the car at a higher RPM. I sprayed 15 bottles through the 135 mile L-98.
My friend sprays his 115K miler LT-1 with a 200 shot..no worries so far. Like Pete said, as long as the fuel is there and be safe with timing, you shouldn't have any problems.

There is always a disclaimer, but at 100 shot, the bottom end should be just fine. You are probably good to 150.

Interesting.
I was leaning towards the gears, but now I'm not sure. I haven't run the car at the track, but it doesn't mean I never will. It's not a daily driver either.
Keep it coming guys. Good input.

It all depends really. What do you use the car for? Do you like to hotrod around? What gears do you have stock (I wanna say prolly 3.33).
PERSONALLY, I'd do 4.10's, because with gears, you have more power ALL AROUND, ALL THE TIME, and it'll make it FEEL like a 100hp nitrous kit.
Then, of course, you're gonna need some sticky tires

stock 3.45 gears.
If I go NOS, would I be looking at needing to get bigger injectors as well? (still have the stock injectors). My gut feeling is yes, I doubt they would be able to supply the fuel required above and beyond my current head/ cam set up....

A "wet" system does not use the injectors for fuel enrichment. Fuel on my nos 5151 kit is tapped off fuel rail. A "dry" system uses the injectorsfor enrichment. I do not like the dry system. Others may disagree.

Injectors and NOS
Ladimer:
No, bigger injectors not necessary. The "kit" is engineered for your application. Like others have posted. Abide by the instructions and all will be fine. Unless your engine makes power at high rpm (5800 +) the gears will not help as much as NOS. I spoke w/ Lingenfelter years ago re. same and he was positive the gearing was not signifigant. NOS will make 150 hp. Gears none (but allow "mechanical advantage/torque application).

The gears would give you a bit of SOP feel ALL THE TIME. But, if you are looking to make your car the quickest possible for the least amount of money, there is NO substitute for juice. Just make sure you know where the closest place to get the bottle refilled and how much they charge per pound.
You would not need to change anything on the car to add N20, so long as it is in good running condition.

Go with the gears. You will get much more acceleration and fuel economy will not suffer too badly. And with nitrous, you have that large pressurized bottle inside the car and right behind the seat

Gears change the multiplication of torque, they will make your acceleration faster, BUT the higher gear ration means you will run out of each gear sooner (you'll have to shift at a lower speed), this could possibly make you add a shift in the 1/4 (and may negate some of you performance increase due to the greater acceleration).
NOS adds acceleration by increasing your torque over the entire RPM range, until you run out of N2O.
I'd say N2O would probably yeild better 1/4 times than 4.10 gears, but I can't promise that...
How about you do both (hey, it's your money, not mine)?

And N20 will NOT impact fuel economy unless you have it armed and your foot on the floor. That's one of the benefits of spray - your daily drive-ability is not sacraficed.

I think part of the reliability puzzle is how much power you are doing now with the head/cam/ header...I agree with the others that normally a LT1 should handle a 100 shot just fine.....but you are adding 100 to an already increased power increase via the head/cam/header.......you need to look at the total power to evaluate how hard you are pushing the bottom end...
People like Lingenfelter have offered top-end packages rated around 415 motor hp using stock bottom ends, so 300 plus 100 equals 400 is ok, but you might be close to 400 now before you add the 100 shot....
Not an answer but hopefully some food for thought..

I was thinking this as well. I'm getting my set up dyno tuned this May and fully expect at least low 400's at the motor. So, a 100 shot on top of that (500 at the motor at least?) is my concern with the bottom end. Most responses thus far have been that it should be safe??? I would hate to pull the trigger, get the NOS, abuse it once, and BOOM!
I would think the gears may be the safest way to go...
Any more insight on this?....
