Re: 4.30's or 4.10

FYI if you are draging on the street at highway speeds the 4.30 's are to much gear IMHO. I had the 4.30's and changed them out to 4.10's because I travel with a group of Mach1's and Cobras. When you are crusin along at 65-70 mph and someone wants to get frisky you Will run out of gear way before you want to and they will walk by and wave at you when you shift into 5th. When you are figuring your speeds remember that 5th is over drive and it's useless in a race. I think with 4.30's top speed in 4th is about 119mph and with the 4.10's it's aprox. 126mph. If FRPP made 390's that's what I would be using.

Re: 4.30's or 4.10

4:30s on street tires picked me up three solid tenths. Some will say traction will be an issue. That is a possibility every time you race, but if you know how to launch the car then your increase ...or should I say decrease in ET will be noticable.

I am so pleased with the gears that I would never consider changing to another size. Yes this is my daily driver.

Re: 4.30's or 4.10

I agree with gears being a great mod for the track. I picked up a good bit with the 4.30's and BFG DR's....I think it was about 4-5 tenths..... more than any other mods I have done. That being said I did find the 4.30's to be a very good choice in the 1/4 mi. and if that was my primary use I wouldn't of changed them out. I just found them to be limiting on the street because the street isn't preped like the track is. It just felt like I was always up against the redline and at times I needed more top end speed

Re: 4.30's or 4.10

Well, I don't know if anyone is still watching this thread, but I just got my 4.30's and moser axles installed today. All I can say is HOLY S^&#! Makes the car feel 500 lbs lighter and with great street manners. Granted you don't go as fast in each gear like the 3.55's but the acceleration is so much quicker it more than makes up for that only drawback. I highly recommend these for anyone who does more around town driving than highway, but also very good highway performance. Not as bad as I had expected.

Re: 4.30's or 4.10

to bad we dont have 9inch rear ends so we can swap out hog heads with diff gears when whe want. I remember my 72 Torino back in 83, on the weekends i had my stock 305s and on the weekend drag race adventure id put my 456 gear in, in about an hour!

Re: 4.30's or 4.10

I put my old 4.10's from the coupe in a few weeks ago and clearly they woke up the car. For a dedicted street car they are IMHO perfect. If I were at the track and running the car on slicks, I would more than likely go with 4.56's. If our engine was a 7200rpm zinger than I would more than likely go with 4.88's or so for the track...

But, the 4.10s are perfect for me on the street...

Re: 4.30's or 4.10

Could someone with the 4.10s take a video of the gages while accelerating? This would help my descition between 4.10s amd 3.90s......

Here are Ford Racing gears for a cheaper price.

Re: 4.30's or 4.10

I am going to install 4.10s soon. I am auto and s/c'ed. I don't see how my car wouldn't run out of gear with OD off in the 1/4. I only got 3 gears... Anyone have the similar combo so I can tell what I'd cross the stripe at in RPMs?

Not entirely true. Did you ever actually wind yours out in 4th and put it in 5th? I did with 4.30s and it still seemed to be pulling quite sprightly to me. 4.30 gears turn 5th into an actual useable gear for accelerating.

It's worth noting that street racing at those speeds is stupid, though. Highway rolls should be left to Supras. :OOPS:

I have to disagree with you. I have wound mine out to 6800 in 4th at least 50 times and let me tell you that if there is another mach just off your quarter panel or a cobra chasing you down when you shift into 5th it feels like they turned on the boost or something. They will walk right by if they have stock 355's or 373's. It might feel like it is pulling quite "sprightly" but it isn't enough to hold off the highway geared cars.

Speaking of zinging, I'm going to have to make ANOTHER gear swap...

He asked about the transmission...not the axle. Not sure what he really wanted the answer too, though.

Re: 4.30's or 4.10

I have had 4:30's in for a couple of months, and it is my daily driver, It's awesome!!! I use 5th gear more than ever, I would mention my MPG, but I would get the , I'm very happy. I would recommend 4:30's, the only down side, I have a little traction issue .
