Thread: 5.0 7-UP Mustang

Tweet

I had Flowmasters put on it the first weekend we got the car.
Flowmaster sound as if they were tailor made for the 5.0 Mustang.

Can't mistake that sound

sounds good to me.... flowmasters have an awesome sound....

I have run into a problem with the dipstick.
I called Lokar and they have one for the 5.0
The OEM dipstick will not go all the way down since I moved it to get the headers in.
Price ain't bad and I like the prods that Lokar makes.

Dip stick is in, Finally!
The original broke off right at the block while I was trying to get it out.
I had to remove the header on the driver side to get down to the stub. Royal pain in the butt to get that thing out.
Lokar unit went right in with a little sanding on the OD.

I can't praise Lokar enough, they make good stuff, it fits, looks good and is cost effective.

I installed a MSD 6ALN I got from Roush Racing. They sell these things dirt cheap. They run them 40 hours and remove them.

I sell them electrical wire for the cars, I don't get a special deal. Anyone can get stuff from Jacks Garage.

Next step?

I don't know squatt about throttle bodies and the like.
I can't light the tires up on the car even trying to power brake it.
It takes off like a rocket when floored, should it boil the tires during a power brake?

"should it boil the tires during a power brake?"

Depends on weight on the rear tires and the suspension setup. I know one thing for sure, it'll boil the torque converter and tranny.

tell me more


You should definitely be able to power brake the stang. I could do mine even when the AOD was on its last legs.

You won't get any benefit from a bigger throttle body. Finish the exhaust. Off road h pipe and some mufflers if you haven't already done it.

The biggest bang you are going to get without a power adder or going in the motor is a set of gears. I would recommend a set of 4:10s due to the extra weight of the vert and the AOD.

You should put the car on the track. Just to get a base line. What do you want to do with the car?

This may be a duplicate post---if it is I'm sorry, got some CPU issues.

The car excellerates very well.

It just seems bog a bit when you try to power brake it.

I have heard that the AOD tranny's are a bit worn at 100k plus miles.
We do not drive it in AOD as a norm around town. We keep it in number two.

There is an old airbase here in Greenville SC, it's now just about totally owned by Lockeheed Areomod. they rework PC3 Orions here.
There is one runway that they do not use, it's about 1.5 miles long and the locals use it. The cops will leave you alone as long as you don't do any head to head stuff. I grew up here and didn't know about it but my son does!

The Mustang 1/4 mile time hasn't change much with all the adders that I have put on it. I was hoping for much more.

Y'all got me scared in thinking that the tranny and torgue converter are about to die!
Will a new TQ and a tranny rebuild make that much diff???

Check into a lyntech tranny.

But yes a fresh tranny with a larger stall would help.

Remember to replace the valvebody with one that will hold out the 2-3 shift.

What is the OEM stall converter RPM on a 1990 LX 5.0?

Enlighten me a bit on the brand of tranny. I have found that a new tranny sometimes is much better than a rebuild with a diff converter. Got web site or something I can look at? Also what kind of bucks we looking at?



I'm a samll block chevy guy, is it roughly the same for Fords?

ford aods are kind of crappy


It all depends what u want to do with the car.

Nice.

I'd like to call them and get some questions answered.


What do I want to do with the car?

First thing is not let it kill my kid!

Second, is scare him enough to make him respect the power.

The little car is a handfull in the rain, he understands that part.

I guess I'm living my youth through him a bit. I want him to have a good performing car that is above the norm. I want to keep the car as original as possible in hopes that it may be more than a regular 5.0. Ford didn't make many of these convertibles in this color and interior combo.
Plus a 16 year old in a 5.0 kick ass Mustang may elevate his possiblility to loose his virginity.
Not to say anything about dad being able have a little fun at red lights!

Craig, let me see if I've got this right....you're building a hot rod Mustang with a soft convertible top for a 16 year old kid.

If he gets this thing crossed up at speed, he's gonna lose more than his virginity.

I honestly don't mean to sound like a know-it-all or smartass, but I've been inspecting drag cars for over 40 years and in my humble opinion, your next addition to this car should be a minimum 5-point rollbar if not a rollcage and 5-point belts before you have to go out and buy yourself a black suit.

tech makes the best point that one can make when it comes to speed and performance....It doesn't matter if your car will run 9 flat in the 1/4, if your not alive to see it then it doesn't matter now does it?

If the boy plans to do any kind of foot stompin then you need to take some safety measures...learned that the hardway myself

65 'round a curve tires screaching and i found myself wrapped up in a thicket of trees with a totaled truck, a case of whiplash, and a sore rear end after my dad got done with me

Learned my lesson and i want to help people learn their lesson before they end up like i probably should have...I'm rather lucky to be alive...65 mph in one of them little 4 banger nissan trucks sliding nosefirst into a stand of trees...not to mention that stand of trees were the only thing holding me from rolling down the ridge and into the creek bed. I'm a lucky one...couple of my friends weren't so lucky... they were tboned by a school bus doin 60 mph with 46 kids in it...

Thanks to both of you for the reminder about the saftey of the car and the driver.

Most people say the same thing, but I have a good kid!

I have gone out of my way to instill in him the dangers of high speed and irresponcible driving.
I have taken him a local towing service that picks up cars that have been in very bad wrecks. He lost a classmate a year ago in a stupid street race crash that killed two high school juniors.
I have inquired into sending him to the Road Atlanta driving school, not for racing but for education on car handeling.
One of the best demos that the local school did her in SC was a contraption that was on a trailer. It had a seat with a five point harness attached to a seat that was elevated on a track. It was winched up the ramp with the person strapped in and released to travel about 8 feet and stop. It simulates a crash at 35 MPH.
It's REAL eye opener!

He has the respect for a moving 1.5 ton piece of machinery and he does understand that it WILL kill him. You know, we sit here typing stuff on how to make our cars faster, more torque, more HP but I am as guilty as many of not thinking about the bad side of all of this tinkering. As they say, it's not the fall that hurts, it's the STOP.

Again thanks for the words of caution. I aprreciate it very much, and I do not own a black suit! Don't want one, EVER!

Good advice about the roll cage.I wouldn't run a ragtop without at least a rollbar. Keep in mind that boys usually wreck at least one car early in their driving career, with luck they live to learn from their mistakes.
