1968 cougar?

i have a chance to pick up a very solid 1968 cougar. how hard would it be to squeeze a 460 into it? i think crites makes headers and mounts. it would have a 9 inch rear also correct? thanks for the help.

No differnt than a mustang of the same year under the hood. Shock towers make it close, very close!

67/68 Cougars that came with a 289 or 302 had an 8" rear axle. ALL BB cars 390,427, and 428CJ came with a 9". The 427 and 428CJ cars had 31 spline axles and N case centers.

All 69/70 Cougars came with a 9". The 351's and 390 were 28 spline, Boss 302's and 428CJ's go the 31 spline axles and N case centers.

Centers could be open, or limited slip. The Limited slip option in 67/68 was the equa-loc, except for the 68-1/2 428CJ which got the Traction-loc. All 69/70 were Traction-loc ptional except for the drag pack cars with 4.30 gear which go a detroit locker.

All the housing from 67-70 interchange. For the most part the above information applies to the Mustangs too (69/70 302's were 8") except never was a factory 427 Mustang in 1968 and 6 cyl. cars got something lesser than an 8" as well as 4 bolt lug (which changed to 5 lug in 1970)

As for putting the 460 in a '68, trim back the shock towers, and expect a tight fit to the radiator. The Crites Gen II mounts and headers is a good kit. If you look through the car build section you will find several conversion (mainly 67 - 70 Mustang) that will give you a lot of good information on the swap.

drag pack had regular traction lock's . auto. trans had 3.91 while the 4 speeds got 4.30 gears

if there was any D/lockers , would have been 68 1/2 428''s , purpose built for the drag strip

Detroit locker was not available until 1970 and only 1970 from the factory and was only offered with 4.30 gears. 1969 4.30 geared cars were Traction loc's

Is well documented, and well proven.

If you bought the car before Nov. 1969 it would not have one as that is when it came available. the link below is the registry for the 428cj/scj cars. Kevin Marti has the full fricken car and truck production database from FoMoCo from 1967 to 1993 and can tell you everythiing about them from the time the order was placed to when it was delivered.

"Detroit Locker" Differentials

Most 428 Cobra Jet fans have heard of the "Detroit Locker" differential, a positive locking differential that was originally produced by Detroit Automotive Products Corporation (DAPCO) and is now available from TracTech Inc. Most of the published literature that I've read says that buyers of the locking 4.30:1 rear end gear also got a gear-driven Detroit Locker instead of Ford's clutch-packed Traction-Lok, but recent research leads me to believe that this is NOT the case! Information provided by Phil Wassil and by Kevin Marti of Marti Auto Works documents Detroit Locker availability beginning around November 1969 - in the 1970 model year! Kevin later explicitly confirmed that "Ford did not produce 69 4.30 vehicles with Detroit Lockers. These only became available in the 1970 model year, as you noted. There was a special designation in the database to tell which cars had these installed". During the 1970 model year, "DETROIT LOCKER DIFFERENTIAL" appears on the invoice of vehicles that came with a factory Detroit Locker.
