I just purchased at auction an 81 LX with a 2300. This is the first Mustang I have ever owned so I will have tons of questions to ask. My goal is to pull the 2300 and drop in a 305 and then through time turn it into a NHRA stocker. So here are my first questions.

1. What parts are required to convert the current 4 lug pattern into a 5 lug pattern? Please list the important parts. I hate to start this project and come up short.

2. Is the K-member the same on a 4 cylinder as a 5.0?

Thanks much

Dave

Sorry nobody answered you yet, Dave. Welcome to M&M, anyhow.

1. The easiest way may be the kit Ford Performance has.

2. The V8 uses it's own k member, IIRC.

-Cheap 5-Lug Front Brake Upgrade-

-Rear Drum (5 Lug) Upgrade-

The 2300 and 5.0 engine cradles are the same. It was the inline six (200ci) that had to be swapped for a V8 conversion.

Thanks to you both. Iread on another web site that the four and 5.0 K member are the same too.

So far I am going to do theese mods to the front end.

1. Make the brake swap using a 5.0 spindle and the Mark VII rotors ad use the 5.0 calipers too. Also I replacing the 20 year plus hoses with braided line.

2. Get rid of the powered steering rack and goto the flaming river setup so I can get rid of the pump and hoses.

Since this is going to be stocker some day I am sticking with the stock lower A arm. Who makes a good bushing replacemnt for them.

One other thing that has me in the dark is the front struts. Who maks a good set of them for drag racing.

Sorry for so many questions. I am a mopar person mostly who has always liked Fords. I guess that old 66 LTD (my first car) got in my skin deeper than I thought

Use the MARK calipers also.

As for the struts, is this a street/strip or strip dedicated car?

You need polyurethane bushings (graphite impregnated) available from PST.

In the beginning this is going to be a dedicated bracket car then later on a NHRA stocker running in G/FI.

Thanks

Well then, I would think of something fairly cheap like LAKEWOOD 90/10 front drag struts and removing the stabilizer bar.

If it's going to be a relatively low-powered bracket car, I'd just put 10" Ranger rotors and drums on it for now. With good pads and shoes, it'll have plenty of stopping power for a 3200 lb Mustang at around 110 mph. You'll eventually want to migrate toward the lighter setups when making the transition to stocker. The Mark VII/SVO setup is pretty heavy.

What's your reason for dumping the 4-lugs? If you don't already have 5-lug wheels, there are plenty of aftermarket choices with 4-lug, and you'll save the hassle and expense of the switchover. As a bonus, it'll be one stud and lugnut lighter at each wheel!

I have about 3 sets of wheels from my mopar setup so buying the wheels is no problem. Can the ranger rotors work on the 4 cylinder spindles and calipers?

Early Ranger 10" rotors (5 lug) are a bolt-on, assuming that you have 10" rotors now. I believe that the only ones to have 9" rotors were the '78 (Fairmont/Zephyr) and some '79 Fox platform cars. Post '86 V8 cars, SVO, and Lincoln all use 11" rotors.

There was actually an early Motorsport kit, no longer offered, that used these 10" pieces for their 5-lug changeover. I could probably find the part number if you wanted to search for a kit.

Something you might want to check before going too far toward the 5-lug is that the Mopar wheels you have probably won't be of the correct backspacing. Stock dimensioned fox cars generally use the 2.25-2.50 backspacing at the front with a 3 1/2" wheel, and 5.5" in the rear for 8" wide wheel, or 6.5" for 10" wide wheel. Naturally, these dimensions may vary, depending on your combination of brakes and such.

Is this the Dave with the Duster by chance?

Yes Mark, It is I. And my duster uses the same backspacing on 10" wels as the Mustangs. Also my 3.5" rims are correct too.

I decided to have some fun with an FI car and figured Ford is far better than the "c" word.

Welcome to the dark side of EFI stockers, Dave. I for one am glad to see you stayed away from the "c" word cars.

It sounds like you're set up for wheels!

Good luck!
