rearend options

[svofloyd]

Ok guys, I've been using search and trying to find some options to go for rearend. The most common i see is either an 8.8 from a TC, or a cobra IRS.

I was curious if there were any companies actually producing any components save for girdle for the 7.5? I was going to see what everyone was running, and what they would prefer to run now, after some experience.

I was wanting to keep the car pretty stock underside. I was wondering if i could get some stronger parts for the 7.5, and then maybe a panhard bar, to help stiffen things up. This is all plans for later, but i was just trying to get a good idea about what people were doing.

I am also a bit sketchy on the 8.8 swap. Does the 8.8 retain the quad shocks? Sorry for throwing the newb question into the lot.

IMo the 7.5 is just junk UNLESS your svo is dead stock and will NEVER make more power.

Mine broke when my car was stock and not even running right!

Unless you are trying to make it %100 original just get an 8.8 out of tc or 5.0 mustang, very easy and worthwhile swap

I'm keeping the 7.5 in my SVO, I just don't drag-race, and have never had slicks on it (and never will)
My silver car has a dyno slip around here somewhere with 322 rw torque, which ain't huge, but is enough for me.

The first time I decide to bolt on a set of slicks, I'll replace the whole rear, until then, I'll keep my 7.5.

not to mention lower mass, and weight, which helps with mileage, and overall car weight.

I've been beating on mine for 10 years now (those of you that have seen me auto-x know what I mean) and I have only changed the fluids twice in it.

YES, there is a company out there that makes a rear griddle for the 7.5 (TA) and if you look real hard, you might even find one of the original ford ones, that Says SVO on the back.

I've been thinking same thing....until I get really serious with the torque just use the 7.5".

I've installed an 8.8 from a TC- 3.55s or 3.73, trak-lok, and quad shock mounts- just drill some holes for brake line mounting and away you go!!

[svofloyd]

Well, I was wanting to keep things both original and the weight down. There is a point were weight is a positive thing, and also a negative. Yea, I would be increasing weight over the rear tires and making her hold more power but then on the other hand, i've made her fatter. Kind of have to sit the fence and decide which is the lesser of the two evils.

I've been searching around the forum and the only place i've heard mention of the templates to use for the 8.8 swap was from a post with eric mentioning they were in the member only section =(. So could I ask anyone if they could help me out with swap instructions? It's something i haven't nixed, but something i am not planning to do like tomorrow. I am still debating on it.

The tc's had 3.55's with the manual and 3.73's for the auto yes?

[SVOeric]

the templates are for adding quad shock brackets to your car. (not the rear-end)
They are only needed if you are adding quad shocks to a early 84, as everything after December of 84 had quad shocks.

I know you have an 84, but you havn't mentioned if it's a slapper bar, or quad shock car. ( I assume it's a quad shock car, since you talk about retaining the quads)

adding a panhard bar will improve performance, but it won't help with the strength of either a 7.5 or a 8.8.

I got a 8.8 from the Lincoln Mark VII. Same axles, same width, same calipers, trac loc, & 3.26 gears. No provision for the quads though, and I used the brake lines from the 7.5 to the calipers. If you don't put the dog bone on the trans it weighs about the same as the 7.5.

[svofloyd]

Yeah, she is a quad car. I infact think she came off the line in dec. The p.o told me the assembly date but i don't remember. So, it should just bolt up, since it is quad shock?

*edit* By using the svo axles/brakes, it should bolt up. Then my next question is, what is he talking about with the 'dog bone'. I don't know too much about rearends.

[onthegosvo]

Dog-bone is a counterweight on the rear end.

when did ford start employing this idea? I don't recall ever seeing that on any of my 9" rears... btw, I usually do older car stuff.(have a 71 mustang m code)

Dogbone(s)

Didn't realize the SVO had 2 dogbones! The one I was familiar with was the "'bone on the bell", the short cable with 2 lead balls on either end (separate from the pedal-to-the-bellhousing clutch cable) on the bellhousing.
That's the l'il booger of which I've learned to have a spare in the glovebox.


A 3.55/8.8 is going to be the future replacement for the 3.73/7.5 presently in my 86. It seems the smart thing to do for a stock 2.3T as well as giving the turbo longer rests between uses to up mpg's.

they been doing that big dampner thing since late 70's ...
