I've never understood that.

People can type but the can't read.

 

Like they said.. header, intake TB, 4.10s, if they are all cam only.. take em up a notch and go h/c.

If you are going for the fastest cam only car.. youwill also need ways to put that power to the ground.. hence a new rear-end and dr's.

Ye who spends the most money wins.

 

Big cams are cool, but if you just want to beat them in a race, spray that bitch.

I hope you're aware of the big debate on here about big cams vs. proper set-ups. Pat G would probably fall out of his chair when reading this thread. XD

Also, I would take PredZ's advice.

 

its funny, cuz even right after i posted that, the first thing out of the next posters mouth was telling her she was gonna need lt's

btw, nice numbers in your sig for a bolt on car

The reason I have an '04 5.7 GTO motor is the original motor let go. When I bought the car I didn't know a whole lot about them and to make a long story short, the motor was down on compression in cylinder 5 by 1/2 after doing a compression test. So therefor, I bought a crate motor from Scroggin Dickey and switched the oil pan, oil galley and oil pick up instead of having it down for a rebuild.

Like I said in the 1st post, yes I am going to do gears and lt's WITH the install, just not sure if I want true duals or a cat back.

The motor has only 3500 miles on it as of the moment so don't believe that I need new oil pump or timing chain. I will be doing 921's and pushrods with whatever cam I go with.

I like the ms3 cam, one of our good friends has that cam and his runs great. He also drives well so that helps out alot. I am not impressed with the ms4 that our other friend has but not really sure if something is not wrong with his car????

 

Sorry ive gotta do it...one of my pet peeves...motors are not just electrical

as per the American Heritage Dictionary:

1. Something, such as a machine or an engine, that produces or imparts motion.

2. A device that converts any form of energy into mechanical energy, especially an internal-combustion engine or an arrangement of coils and magnets that converts electric current into mechanical power.

 

you siad you want the best biggest cam, look at the top list of cam only cars and I beleive the T-rex has more members than any other cam only car.

 

I just want to reemphasize what a lot of the guys are posting. Bigger is not always better. Your street manners will suffer with a larger cam unless your tuner is a genius. Will he/she take the appropriate time to log data and get the tune down perfect? I doubt it. Look at my setup. I can stomach my setup, but that is as much as I will take for a street/strip car. I also want to drive my car to work ever so often without surging when the AC is on. My new setup will include a smaller custom grind, ETP heads, ported FAST intake, and all the supporting mods. Maybe even a forged bottom end for a shot of the giggle juice. All in all, my new setup will rape my old one even if I thow on the heads now. Reason being... power under the curve. Peak numbers are nice, but not everything. Just food for thought.

Take a look at this thread.

BTW If you have your heart set on a donkey dick camshaft let me know. I have a NIB camshaft with comparable specs to TREX that I need to get rid of. It has put down better numbers that the TREX. PM me if you are interested.

 

care to give out the specs

 

My first dyno ever she put down 365rwhp on LS1 intake and bolt-ons. It was a spike so more like ~345 but since then on two separate dynos she's out down ~356rwhp/tq.

Back to the thread. You can get as big a cam as you wnt as long as you get the right tune then you will love it.

 

Yes you are correct, but from an engineering standpoint that would be considered incorrect. Im not trying to start a flame war, just what I have learned.

smok'nWS6 You do know that a 04' GTO 5.7 is the same thing as everyone else has right? Im not trying to be mean, but just want you to know that its just an LS1 which is a sweet engine. Good luck with your build up. Keep us updated.

 

You also need to consider if flycutting your pistons will be necessary with any of these cams. It's not a big deal to flycut if the installer knows that they're doing but you have to remember if you need flycuts they'll be pulling the heads (vs. leaving them for a regular cam swap) and that'll be extra time and labor involved with the swap. Regardless, when you're talking about cams like the ones you listed it's always a good idea to measure piston to valve clearance, especially on a 6 speed. It's not just the sheer duration and lift that effect piston to valve clearance but also the lsa and advance in the cam.

It's good that you are planning all the supporting mods as well. Don't forget about a clutch and your rear is gonna be on borrowed time if you start putting drag radials or anything on it.

Personally I'd say if you're going to keep the stock heads and intake then pick a cam in the mid 230's and if want more power than that put a safe 100 shot on top of it. That should make for a simple install with no p to v issues, good driveability and torque, a useable powerband where you won't have to spin it to 7k to make power, and spray is the best bang for the buck when making power.

Good luck and keep us up to date on what you do.

 

I am an engineer....

 

If you want a huge cam,
1. Find a good tuner.
2. Good Longtube headers with duals preferably
3. supporting valvetrain (springs, locks, retainers ect...)
4. ls6 intake minimum, fast 90/90 combo preferred.
4. rod bolts
5. 4.10 or lower gear (possible rear end upgrade)
6. Clutch
I've seen several TREX cam only/ heads/cam videos and they are spinning their motors over 7,000 rpm. One video in particular stood out to me. A 6 speed Z/28 with a 4.56 gear. That cam loved those gears.

MS3 if you want to spray it. Terminator's white SS has proven this theory over and over again.

 

yeah basically setup and tune has nothing to do with how good the car runs, so find the biggest cam you can fit, that will make it go.



flycut a little bit and stick a tsp giant in there.

 

I've got a '00 WS6 as well and all I have is: Kooks 1-3/4 race headers, Kooks catted-Y, GMMG exhaust and the MS4. That's it. The car is wicked fast, sounds awesome idling, and you will cry tears of joy when it gets over 3k rpms WOT. There's my recommendation.

 

i'm hoping your making fun of a different poster lol

 

Is that Ford Motor Company or Ford Engine Company? I guess all Fords are electrical powered.

Just do all bolt ons and you can run 11 something just like everyone else does !! But, don't believe everything you read because it could be a lot of BS.

 

Damn! I came in hear thinking "girl for the win" meant literally, the fastes car gets the girl. I'm sooooo dissapointed.
