the s/c comes to about 1.5k more but with alot more HP, i dont track the car, and maybe a 1/4 mile here and there once a year. i personally think the later will provide a more "FUN" vehicle....
ill do all the work myself.
current setup is

Spinmonster, who has a well designed H/C/gears, recently helped install a S/C on another member's car. There is a good post about the process and he does a nice write-up comparing and contrasting the feel between the cars. I'd guess the post was about a month ago if you search for it.
I like S/C cars but IMO, H/C/gears provides plenty of power for the street. Your needs may vary. With the difference in price, you can get some good tires to use the power.

I think that the Cam/gears is more fun to drive... even if it makes less power.... Plus, if you look at track times... you will find more people with H/C/I in the lower times than the SC's.
If you want to just be able to stomp on the gas and go... then get a SC. If you want to have fun with your car, get H/C/I.
Just remember that; With that SC you are going to be spending serious money on tires... No point in having alllllll that power of a SC and not be able to get it to the wheels. This is something to think about.
Plus, a SC optimal range is 50-150mph... How often do you drive there? I personally prefer having the power down low and can get on it from anywhere... Just my .02
I nearly knocked myself trying to decide which route to take. What makes it even tougher to decide is there are some fantastic S/C kits out there (ECS, A&A, Maggie), and many proven H/C/I combos!
With the cam you are picking I would go S/C. Street tires will be the thing that holds any car back so get the best you can. I would still gear it and dont get so high a boost with street tires that are near stock sizes.
If you go with a max effort H/C car with gears, you will likely still be limited too by the tire if it isnt an r-compound. Being a daily driver, I doubt you will pick anything that will stick well.
If your swing thing is roll on races to 150 starting at 50mph then up the boost. Nothing else will compare to that speed range performance.
I like the ECS novi 1500 kit the best for its civil sound, uncivil power, and degree of engineering. With gears its all any daily driver would want. Andy at A&A also has a good starter kit that doesnt require an oil line tapped into the oil pan.
I can do any install myself and since my H/C package cost me 1700 total to do myself, I dont vote on such things with the same set of criteria as some others do. In the mountains, I will be H/C/Gear+s/c+a lil nitrous since I already have it.

No heads in the poll, if heads were added, the prices would be identical...
Depends on the head. Craigster05's total H/C install cost him 450 bucks after he sold the FAST and the stock heads to cover parts. That package will make 470+rwhp/430rwtq on a stock geared car. Not many street tires will be able to hold that even in second gear.
I would get gears first and then get the s/c and do not up the boost before seeing where your traction level lands. Power spins tires not gears so dont get caught up in the bigger dyno number from small pulleys/more boost, and then thnking handicapping the gears will restore traction. Gettng gears will make sub 3500rpms more fun on the street and adds a degree of low end immediacy that boost alone donest give you. Getting gears and raising boost in proportion to traction will make you end up with a fast car while big boost, no traction, will make you slower than stock everytime you touch the gas pedal.
As a DD I 'd go with the S/C you won't notice its there until you step on it. Cams can have some surging that might get annoying in stop and go traffic everyday.

with some bigger cams, I agree. With a 224 cam there should be no surging from 1200 rpm and above with a tune. A really good tune can get it down lower.

on the 224 cam having basically no surging or driveability issues.
Can't really help on which way to go, I did both and love them both.
this is a little off topic but, just wanted to here from the veterans that already have gears....
just going on actuall physics here:
gears multiply torque.
so how does adding gears make it easier to put power to the ground?
not arguing with anyone,, just wana here your thoughts...

Go in a high power car with gears and a good tire to learn about it. All you get from a nay sayer is an opinion based on nothing. I have zero wheelspin even in first on a launch all motor (480rwhp) and great traction in all other gears now with the R2's. Second hooks perfect with 560rwhp ON A 70 SHOT. Anyone that thinks gears dont mix with power has street tires or doesnt have gears.
I have a Z51 with 4.10's and anyone who wants a demo can come by and go for a ride to dispell the myths. I spank higher HP cars without gears all the time. My car performs on the street where you will run your's. The combo of parts is important. Dont take advice of gears or gears + high power from anyone that doesnt have them. They have no basis to be portraying facts when they are touting opinions based on nada. Go in a car with the mods you want.
s/c since it's your DD and it's a z51, so it's already like havin 3.90 gears in a base car...I don't understand the theory that gears help put power to the ground and I have 4.10s

The other thing which may or may not be a problem for you down the road is passing an emissions test. The s/c can often be made to honestly pass emissions and in fact many superchargers are sold in CA which have CARB numbers, effectively certifying they'll pass emissions tests.
There's no way the heads/cam/headers/FAST solution will honestly pass an emissions test.

Base kits and 4.10's are loved by some that have them. He should go in a car with them to decide himself. Off boost FI cars with base kits arent the power house some think they are. Some found that the power in the idle to 3500rpm area was a bit lacking on cars with 550rwhp up top and not much down low.
Not understanding what the gears on a Z51 car with an S/C isnt a reason for him to not decide for himself in a car with that combo. I think its reasonable that he experience it before knocking it. He can decide for himself.

He is already adding headers so let's set visual aside. Plenty of LS1 F-bodies have made it through the CA tailpipe test with a 224/224 114 cam. I know others who over the years have made it through either other states tailpipe or Canadian tailpipe testing with bigger cams, although not monster cams. A higher idle, carefull tune, and functional cats will allow the size cam the OP is looking at to pass.
I agree that a S/C is basically a slam dunk to pass if you leave everything else stock.
