Hey everybody, getting a Vortech V-SQ Polished Kit with SCT 90mm mass air flow sensor, Siemer Deka Mototron 60 lb. injectors and a Steeda oil separator kit. Don't know which spark plugs or pump yet for my 2004 GT. Now my question is are my 4.10's too much for this setup? at the track I will be using 275 DR's or if needed I'll upgrade my rear end and suspension to stay with the 4.10's. and slicks.

Thanks.

P.S I know I Searched and everyone opinion is different about different setups

as long as you're not building the motor to go much more than ~400RWHP, i would say they're just fine.

why the hell are you using 60lb fuel injectors?

I have 4.10's and a vortech and I don't like them. I'm shifting to 5th at the end of the quarter. If you don't race the 1/4 then go for it.

Never know when your gonna upgrade to 1000hp.

How often are you really gonna be at the strip? If this is a car youre going to drive around often I'd say 3.73's should be plenty. If its mainly a strip car hell might as well get 4.56's.[8D]

that's what he's including with the kit, should i stick with the 42's?

I will be using this car everyday and track use every month or so at mustang challange. I don't plan to go over 400 HP probably be in the 370-380 range.

beings u already have them.Its doesnt really matter andif your think there to much then just step it down to 3.73.Dont change them out until u c what its like

i dunno.. i rode in an 02 (i think) GT with a vortech and 4.10s and it seemed perfect. i think he had high 300s WHP. i was going to switch after i did my build, but breaking that 500 barrier, i'm glad i went with 3.73. i may be stepping it down to 3.55.

Agree totally...At some point in power RWHP over 400 IMO ...a lesser gearmight be needed especially if your running outof gear (in fourth ) in the quarter.I've run 113 mphin fourth with no problems(yet) hitting the limiter.A cheaper and easier alternetive is a taller tire.Next for me will be a tire with a height of 28 inches(instaed of the DR as of now with a height of 26.1).....if and when I ever hit a 500RWHP a 3.73 and a 28 inch tirewill prob be that ticket.
