Rear end that can handle mod power with the 4 lug pattern

Post #1 by Timmy66 » Sat Jan 12, 2019 9:03 pm

I have a 1966 mustang with a 200ci 6 cylinder I plan on turbocharging and I was wondering if anyone knew of a way to keep the factory 4 lug pattern but maybe in a better rear end that can handle the power?
“What motor is in your mustang a 302?” it’s a six cylinder “oh” I’ve had that conversation some many times ready to build a car that I can use that to my advantage because you know “it’s just a 6 cylinder”

8.8 from an 87 thunderbird turbo coupe or 86 and newer v8 mustangs would be good to look into.

Thanks I’ll have to look into them because I really wanting to keep the 4 lugs but not have the rear end explode the first time I get on it

I believe the 8" out of a 70-72 Maverick has this upgrade.

Unless you really need to be able to launch consistently under boost, an 8" rear should be sufficient. The early 70's Maverick 8 " is bolt-in simplicity and strong enough for most uses. . I run a Maverick 4-LUG 8" in an '61 Comet NA 250 Tri-Power and has survived plenty of full power launches. I retained the 4-LUG theme with 71 Maverick 4-Lug front spindles with a disc conversion and 65 V8 steering components. Only issue has been terrible wheel-hop remedied with Caltrac type devices on the 2" '61 springs.

'61 Comet - 3 CARBS, 4-LUGS, 5 GEARS = T5 / 3.80 POSI / Traction Devices

8.8 is a real good axle however their 4 lug axles & wheels use a different bolt spacing then your 1966 Mustang 4 lug pattern. If you want the front and rear wheels that are a match or you don't want to remachine the front hubs so they do, then the early Mavericks / Comets 4 lug 8 inch is a good match, it might be the better way to go. Good luck :thumbup: :nod:

My uncle owns a junk yard and has a 1970 Maverick with the 4 lug pattern wouldn’t it be the 8” the cover looks different from any 8” I’ve seen

Yeah that's a no then, many of the very early Mavericks 1969 1/2 to 70 and maybe even some early 1971 models that had a 170 or 200 six engines used the 7 1/4 inch axles with a bolt on rear cover just like the Falcons and Mustangs. You will need to find one that came with a bigger 8 inch axle latter 1970 manufacture date, to up to the end of the 1974 models for the 4 lug 8 inch axels, starting in 1975 and to end of production they all were the 5 lugs 8 inch axles. Good luck in the hunt :thumbup: :nod:

The Pinto and Mustang II has a 4-1/4" bolt pattern, not 4-1/2".

I did not provide the information to satisfy a 200ci turbo 4 lug too small brakes pipe dream that will never happen.
The Pinto 8" housing and 3.40 pumpkin info would be a good find today for a serious mechanic.
Of course I would pull and scrap the 4 lug axles no matter the bolt pattern.
I have been running the same 8" 3.25 5 lug rearend since around 1980 or so. Same goes for the front spindles which now have Scarebird 5 lug disc brakes. A good running 200ci needs 5 lug brakes.
No puny 4 lug brakes or stroking people with wild turbo dreams for me.

Good to note 4-1/4" disc brake wheel bolt pattern of later 70's (Pinto/MII/Fox Body) vs 4-1/2" used on Mustangs, Falcons, Comets thru mid 70's . Available simple bolt- on upgrades for early cars like my '61 Comet use Maverick 4-1/2" 4 Lug Spindles with disc brakes and Maverick 4 lug 8" rear w/drums. Most available later 4 lug rears' are the smaller pattern and spring brackets probably need to be moved.

have fun

I have a '70 8" out of a Maverick with 4 lug in my '62 Ranchero. Center section is the same as any Ford 8", no rear cover.

A '70/'71 Maverick with a 170 or 200 will be 4 lug, 250's came with 5.
