What mods?

I have a 1997 camaro ss. It has 305 hp. I want it to sit around 450-500 hp. What is the best thing to do. I don't want to supercharge it. Any help would be appreciated.
P.S. I'm new to this site and I've only had my camaro for about 4 months.

Re: What mods?

Walbro 255lph fuel pump and a NX hitman 150 shot should get you to the 450 horsepower numbers easily...Headers, catback, CAI, 52mm TB should boost you up a little as well and should "suit" you for awhile i'd imagine.

Best thing about all of it? You still have room in your engine bay...#1 reason nitrous is awesome. Fuel economy when u need it and plenty of hp on demand...and you just have to run a couple hoses and electrical lines.

Re: What mods?

a bottle is cool and all, but I dont want to get the hp that way. I want it to be raw engine so the horsepower is always there no matter what.

Re: What mods?

Then talk to Lloyd Elliot, he's the man for big N/A HP, he'll set you up with a sweet Heads and Cam package, probably could get you real close to 500+ hp if you wanted.

From Lloyd:

Below is a basic run down on the head and cam packages. The best package will depend on HP goals, budget, rear gears, stall size, future plans, emissions, driving style, tuning ability, existing components, etc., etc, A phone call would be best to make sure that we can talk through these things and get a package that will work like you are wanting it to and also make sure that you have the complimenting parts to make each set up work.

I offer cam and head packager from $1100 to $1650.

-----------------------------------------------------------------------------------------------------

LE1 cam pulls from 2000 to 6200 RPM and should make 370-390 RWHP with matching heads, 30 lb injectors, 52 TB, 1 3/4 LTs, No cats, good tuning, etc. The heads are ported using stock valves, performance valve job, back cut valves, CM 612 springs, retainers and locks, milling, cleaning and assembly. These heads flow about 255/180 with a 195 cc intake port and stock LT1's flow about 215/150 with a 170 cc intake port.

Heads and cam are $1100 (plus shipping). This has the RPM range of the Hot Cam, CC 305, etc. but makes more HP and TQ over these cams through out the entire RPM range. This will work with any gear and converter but the track times will be better with a stall and some gear.

-------------------------------------------------------------------------------------------------------

LE2 cam pulls from 2200 to 6500 RPM and should make 400-420 RWHP with matching heads, 30-36 lb injectors, 52-58 mm TB, 1 3/4 LT's, no cats, GOOD tuning, etc. The heads are ported and machined for larger Ferrea 2.00/1.56 valves, matching springs (Comp 987/977 springs and Ti retainers or Bee Hive springs and CM retainers depending on lifter type and EXACT cam specs), locks, locators, milling, cleaning and assembly. These will flow about 270/190 with a 205 cc intake port.


Heads and cam are $1650 (plus shipping) and will need GOOD tuning. This has the RPM range of the CC 306 cam but will make more HP and TQ at peak and across the board. The REAL difference will be the LE2 cam will make TQ in the 2500 RPM range and the cc 306 doesn't start until way past this.

-----------------------------------------------------------------------------------------------------

LE3 cam pulls from 2600 to 6800 RPM in a 350 (2300 to 6500 RPM in a 383) and should make 410 to 430 RWHP with matching heads, 36-42 lb injectors, 58 TB or mono blade, GOOD tuning, etc, etc, etc. These are the same heads as above. This type of RPM requires a lot more spring pressure and will also need Comp R lifters to handle the spring pressure.

Heads and cam are $1650 (plus shipping) and will need GOOD tuning. This cam is similar to the GM 847 cam but makes about 10 more HP at peak and starts making HP sooner. Makes more HP and TQ across the board. Needs gear and converter to work well in a 350. Pretty much a racing cam for the 350 or a good street cam that will act like the LE2 in a 383.

-----------------------------------------------------------------------------------------------------

Everyone has a different opinion about what is streetable and what a safe RPM limit is for their engine.

If you are looking for just cylinder heads and with out a cam, the heads are priced at . . . . .

$750 for the LE1 heads only
$1300 for the LE2 heads only
$1300 for the LE3 heads only

Give me a call and I can help you pick a combo that you will be happy with.

Lloyds website is www.eportworks.com

Re: What mods?

Also, I'm not a mechanic and I don't know how to install all of that. How much would it cost in labor to have someone install the head/cam package?

Re: What mods?

Around 500hp at the flywheel.

Instead of reposting try to edit your last post, occassionally youll get some moderators on your rear for overposting.

Cost wise, I suggest doing some bolt on mods and getting used to your car, then doing the work yourself. Labor wouldnt be cheap..I'd expect at least $500-700. Plus there are a ton of Cali F-body guys who would probably help you for little or no cost.

Ya, I am posting it as a kill in the kill section.

Re: What mods?

The website said that you need 4.10's for the package. Is that the gears? And is there any other supporting parts that I need to purchase to make my car compatable for a package like this?

Re: What mods?

Well gears I think would help, but I dont think youll necessarily need 4.10's, which are the rear gears. Stock you have 3.42's. The supporting mods are in the lists of LE packages above. Bolt on mods like catback/headers/CAI are things you should try to do first, then 52-58mm Throttle body, better clutch, higher rated injectors,etc.

Re: What mods?

Any recommendations on the throttle body, clutch, and injectors?

Re: What mods?

Clutch im clueless as to what to go with.

Throttle body --i would go with AS&M (Arizona Speed and Marine) and size depends on your budget...if you get a 58mm throttle body you have to port your intake manifold for the larger size as the stock intake manifold is matched for a 52mm throttle body stock.

Injectors...i'd reccomend some Delphi Injectors for the LE3 Package, if your looking at the LE2 Package some SVO 30# injectors should do you fine.

Re: What mods?

Depends on your money situation. The stock TB can be bored to 52mm for low cost. Clutch, idono I am an auto, but try a search. Injectors, its your choice, again cost is the limit.

Re: What mods?

Thanks for all the help, by the way, cost is not a big issue.
