My67_fastback · January 8th, 2007, 05:10 PM

what did the 289 67 mustang have stock? an 8 or 9 inch rear end?

GreenFaleen · January 8th, 2007, 05:20 PM

Not sure but if you wanna check the 8 is flat on top and the 9 is rounded

I have seen both

My67_fastback · January 8th, 2007, 10:07 PM

by top do you mean the lid you can see from the rear or the actual top?

GreenFaleen · January 8th, 2007, 10:38 PM

the actual top like get under the car and run your hand alone the top of the differential if it is flat it is an 8

Could've been either one from the factory.
Big block cars ('67 was first year for FE's in Mustangs) had 9" rings.
Mine did.
MG

ya mine was a c code factory 289 2 bbl, but it was in so many dif hands and didnt have the origional 289, plus it had been drag raced and has air shocks (stock? i dont think they are but idk) and someone added traction bars and a dual exhaust with glasspacks along the way. its possible it has been upgraded to the 9 inch i suppose

I would say it's an 8 unless someone was doing some really hardrcore stuff with it would you need to upgrade to a 9 inch. I mean i was lookin into getting an 8.8 for my jeep so i upgrade from a d35. just my two cents . . .

My67_fastback · January 12th, 2007, 03:13 PM

well i dont know if i need to go 9 or not cuz ive just completed an engine swap. ive got a 351w pushing 350hp and 400+ lbs-ft
