Topic: 68 428CJ sway bar

Would a 428 equipped car be built with the same GT group parts ( springs + shocks ) as a 390 car except for the spacers and a 15/16" sway bar ?

Allot of things play into how a car comes equipped (individual parts) think the first step is comparing like vehicles - same body type, trans, time of year, air conditioner ....

Looking at Buildsheets (don't have any non- Shelby S code nor many non-Shelby R codes) I see a few differences between what appear to be similar cars but that was with just a quick look But those same sort of differences can be found between one 428 equipped 68 and another, looking at 68 Shelbys as examples

Thanks Jeff.

Good point . I have not a viable explanation why they were used on Cobra Jet cars but not on a non Cobra Jet like a GT 500 in 1968 . Anybody got a idea?   

Just a hunch. The GT500 was the first vehicle to use large sway bar with the C8AE balancer.  I don’t think it really became known until the car is where you store while I’m by that point it really wasn’t a service item and they just decided to make a correction on the next model which was the KR   With the cast iron intake and larger exhaust manifolds it was easier for the KR to push down and hit the way bar

Tim, I don't think that was it exactly but with the same result . The 67 GT500 used the 427 style C6AE balancer which is dramatically larger diameter then the smaller C8AE. The problem was actually less in 68 then 67 but still a problem. The cast iron intake and heavier passenger side exhaust no doubt didn't make things any better as you mentioned.  I think it must have been a matter of Ford not getting around to putting a band aid on the problem until the Cobra Jet /KR went into production and the GT 500 was discontinued . I think that is basically the same thing you said. The problem was solved in 69 by re designing the bar.

Did the KR and the GT500 use the 15/16" sway bar ?

Yes even the GT 350 did .
