depends on how much boost(horsepower) you plan on having and how you plan to drive the car. An E-Force 554 HP(flywheel) with their canned tune, will give you around 475 HP at the wheels and doesn't require opening up the engine or adding any supplimental fuel add ons, such as a Boost a Pump or a fuel pump from a Z06.

Auto or manual? My dad ended up missing a shift after he installed his procharger and it bent some rods and valves. Just a good idea to upgrade the valves, pushrods and springs/retainers before anything like that happens. It rev's up a hell of a lot faster with a supercharger installed so it may happen.
I will say that after he did the damage and installed the parts its helped a lot. I've tapped the rev limiter a few times on accident myself and it bounces right off with no issues. I'm not going to peg it like I did my Mustang but its nice to know its there just in case.

Mines held up so far. No signs of slipping yet. The stock clutch is supposed to be pretty strong and definitely not the weakest link. Upgraded valvetrain is a huge improvement. I was getting on her coming home from work and accidentally hit the rev limiter twice. Both times where in 2nd where she spun the tires more than I thought she would.

When it come time to sell the car, it's cheaper to remove a blower and then sell it separately then to remove a cam,etc and try and sell it separately(labor the remove a cam costs more then what you can sell that used cam for). You might save a few bucks up front, going with a cam, etc, but when it comes time to sell the car(and no matter what people say, at some time in their life, that car will be up for sale) you will get more of your MOD money back with a blower.
Having a car with a hot cam can lower the value of the car(vs a stock car) when time to sell, as it decreases the number of people that would be interested in your car.

Not everyone is interested in having the biggest dick on the block. I paid a hell of a lot more for my Z06, over a LS3, and it has only 450 at the wheels. Sure, you can get 475 at the wheels with a cam, etc, but a blower will make for a better package, when considering table manners, gas mileage, and horsepower.

What are you talking about?
A very tame, VERY streetable cam package will make 475 in an LS3 all day long and cost about 1/8 the price of the E-force.
If you are shooting for under 500rwhp then FI shouldn't be the choice.

With the LS3 it's fairly easy to make 475whp. I can't see the reason to spend $8k to get there when you can do it for less than half. If you are looking for 550+whp then it would be worth the cost of F/I.
These engines will handle 600whp and remain reliable. You must keep on top of things like oil changes, swapping plugs, cleaning filters more often. Also a tuner that knows FI setups and making sure you address any issues, CEL's, etc immediately.

So you can de-mod a supercharged car but not a cammed car?

Now you show me where I can get a turn key cam, etc including instalation that will produce 516 rear wheel horse power for 1/8 of the cost of $8995.95 and be a friendly as the E-Force. Kinda overloaded your ***, didn't you? 516 rear wheel horsepower for ~$1125 from heads and cam and headers... LOL.
In fact, Lingenfelter has a 525 BHP(flywheel) horsepower package(440 HP at the wheels) that has heads and cam for $9,995. So the same company that has a E-Force package with 600 HP also has a head and cam package that produces 76 horsepower less at the rear wheels and costs a $1,000 more then the E-Force.

Well Lingenfelter(not a Bubba shop) will do a turn key 599 BHP E-Force for $8995.95. If you wanted the 554 HP version, I suspect it would be cheaper. They get 516 HP at the wheels on a Mustang dyno.

You remember that you were talking about 475 horsepower, right?
I overloaded my ***?
You can do a full cam kit, installed and tuned for 2k or less at most speed shops. OBX headers are about $1000 installed. I don't care how much lingenfelter overcharges for their heads/cam setup. You're paying for their 3 year warranty there...not the parts.
~3k installed into an LS3 and you're making 475rwhp.
Right, 1/8th was a gross exaggeration, but 30% of the cost is pretty reasonable.
475rwhp is stupid low for a forced induction setup. Now you want to talk about over 500rwhp for forced induction? Well, I already commented on that....

I gave examples of the two versions of increasing the LS3's horsepower, out of the same shop. That's the most accurate way. Now if the OP is a very good machinist, I guess he could fabricate his own cam, do his own heads, do all the installation and really save some money. But then he could also fabricate his own supercharger from scratch also and really save some money vs buying one from Edelbrock.
But, if he's wanting additional horsepower and wants someone else to do the work, then comparing Lingenfelter's cost of the cam/heads package to their E-Force package is comparing apples to apples.

You also don't need heads to hit 475rwhp. A very mild cam will do it in an LS3. If we wre talking about an LS2 it would be a different story because then you'd need heads and a FAST intake, which is another 3 grand. Not necessary at all on the LS3. You can do it with a high mild/medium (22x/23x) cam and longtubes all day long.

Not really...their heads/cam package has a HUGE mark up due to getting their 3/36 warranty which doesn't come with the basic E-Force kit.

You can make cheap high horsepower all day long, but doing it with reliability is questionable. Apparently Lingenfelter knows something about horsepower vs reliability vs drivability with cam/heads only packages and chooses not to go the cheap high horsepower route. They have a reputation to maintain.

Then I must assume you consider Lingenfelter a Bubba Shop that doesn't know what they're doing. They feel heads are needed, along with a cam, to see 440 rwhp, so that they don't have to run a radical cam. They also don't offer an engine package with cam/heads above that horsepower. Maybe they don't feel a cam/heads engine is that reliable at the higher horsepowers so they don't offer one. I really doubt that they would offer a 3/36,000 warranty on their engine packages if they felt it was going to be a liability to them. They offer plenty of other, higher horsepower packages with superchargers, but not with a cam/heads only package.

I don't think it has to do with reliability. They have a strong emphasis on building packages that retain stock driving characteristics and economy. The GT-11 cam is what they have used for years since the LS1 is very tame, and puts out low peak hp numbers. I'm not sure why they decided to port the LS3 head though as that head already has huge volume runners, and most independent tests on ported LS3 heads don't show much gain over stock especially with a very mild cam.
