I got a good deal on a set of ford motorsport 456 gears and thought I would give them a try. Well I tried them last night. My motor is a 355 Ford with nitrous a cage , frame and 4 link.
My grandson was with me and he said " Grampa aren't you going to shift"? No Kyle I am in 5th, I was not crazy about the gears, 1st with 3.27 low was rediculous, I was through the gears before I knew it.
I will probably pull them back out.

Fun for about 11 sec right? :)

Don't know how guys drive around with 4.11's and no O/D. :confused:

Hi Norval , I installed a set of 4:56's in my son ss nova a few years back at his request . It was not very long before he returned for the same reasons you cited in your post . They pull like the devil but , Just not a very practical street gear .

Geo :seeya

Norval it sounds like you now need some taller tires in the back to compliment those gears ;)

Is 5th an O/D or 1:1 ?

My dad had 4.30's (factory) in his '68 Hemi GTX. All I can say is "Hold On" because once it hooks it's GONE!:eek:

You should notice quite a difference. :yesnod:

5th should be 0.6 in the stang.
... but this is Norval's, so it has likely been modifed from stock.

:thumbs: :cheers:

I once drove my Z28 with a 9" converter, 4.56s, and 26" tires 330-miles, ONE-WAY, to a car show...
:crazy:
Since I rarely drove that car on the highway, and kept it below 45-50 MPH in-and-around town going to the strip, I thought they were a blast!!!

(with 3.27 1st gear)

With 4.56's, the final drive ratio in 1st gear-- 14.91 to one :eek:

With 3.73's- 12.20 to one

With 3.27's- 10.69 to one

This is quite a steep 1st gear FDR with these 3.27's!!!!! Nevermind with 4.56's!

(thinking outloud here!!)

I bet you can't really even use 1st gear, right? It reminds me of the granny low 1st gear in a U-Haul truck I once rented!!

I run 4.11s with my 4 speed (no overdrive) and don't think it's bad. I run Mickey Thompson ET Streets (28x11.5x15s). I usually tach about 3000-3500RPMs on the highway which with open headers makes for an interesting drive. Around town and down the 1/4 mile they sure are fun though.

Norval:
3.27 first gear and a 4.56 rear gear is an effective 1st gear of 14.91! That's a "tractor-like" 1st gear. The 3.73 rear gear is about perfect with your 5 speed. You still pulling the front wheels off the ground with that Mustang? :)

Here's an interesting chart from chevy hi-perf mag

:iagree: :yesnod: ....like these --->

The transmission is overdrive so the final ratio in 5th is 3.1 which isn't too bad. The worst thing is 1st gear, you move about a car length, are revved out and pulling the next gear, It is a stump puller, alot more gear then I need.
With the 373's and slicks the thing would pull the front end on launch. The slicks are gone for new Goodyear F1's which I got a good deal on earlier this week. You can drive around town at 30 mph in 5th.
It was just something to try and keeps me in practice changing gears. Once you do a few rearends they are really nothing and can be done in an evening.
I will give it a summer, this is the 3rd car I used 456 in. In my vet the 4.11's were just too low in first but I don't mind reving the ford up. While the motor has only 3 or 4 summers on it I would like to pull it this winter or next and stroke it to about 400 + with alot more compression

While this is my post I want to show you guys a picture of the walk behind snow blower my son put together from spare parts, The motor is a 700cc 18 vee. It has a open header, a road gear that allows you to jog behind it, a twist throttle so you can blip the throttle and a monster tac.
He was just having fun, Here is a picture of it.

No wonder you like winter so much

:lolg: :lolg: :lolg: reminds me of that Pryer movie, MOVING i think it was called guy had a 350ci V8 w/ zoomies on a walk behind mower :hurray:

Nothing wrong with a 4.56 or a 4.11. I use them both. A 4.56 will be a little quicker, but the 4.11 will probably out MPH the taller gear. I could never see the object of building a fancy motor and then using a low reving hydraulic cam and 3 series gears that will allow you to do a buck fifty on the freeway and wonder why it wont do well in the quarter. :confused: If you build them correct, it will perform correct :D :thumbs:

The overdrive makes the 456 actually perform like 3.1 on the expressways which is fine but there is such a thing as too much gearing out of the hole. My vet with the 4.11's and 3.27 first gear just never had a chance to start pulling, it just spun even with big slicks. In this case I was much happier with 308's. I still spin like crazy if pushed but at least I can clear the intersection without shifting into 3rd.
I have had 3 cars with 456, a couple with 411, one with 355 and my present 308's in the vet.
If you don't can the power you can help with gearing but if the power is really there regardless of the gears the car will put.
My 10 to one in the vet will easily outpull the 14 to one in the mustang regardless of the nitrous and 355 motor.
What the mustang has that the vet doesn't is the ability to hook. Given equal tires/slicks the mustang with holeshot the vet plus do a wheels up launch.
Guys I have driven/owned cars that explode out of the hole, come out at 6500, hook up solid and pull second at 7500 and do it all in a car length and my vet has never hooked like this. That was another ford as well.
The gears are in for now, I keep looking for another gear all the time but they will stay in for the summer but not sure if they will survive the winter.
