View Full Version : Disc Brakes?

05-22-2005, 11:43 AM
I just recently purchased a 1967 Rebel 770, it has a 390 with a c-6 transmission. the car is in very good shape, but it has 4 wheel drum brakes, i was wondering if there is anything compatable with the rebel so i could at least have disc brakes on the front. thanks Clint

I think the spindles from a later AMC will interchange. There is an article with info re disc brakes interchange on the Eddie Stakes website.
BTW. I believe your trans would be a Borg Warner torque command.

http://www.planethoustonamx.com/ has the disc interchange article.
Take care of that Rebel!

Thanks for the article, i'm currently trying to find the block casting numbers, i'm trying to figure out what the 390 is from, and as for the tranny, i haven't had time to try to identify, but i was told it was a c-6, any clues to identifying the tranny? Clint

If its a c-6, it will say FoMoCo on it somewhere. The BW will have a tag on its side stating Borg-Warner I believe. If its a c-6, then its a custom install. C-6 is STRONG.

Brakes upgrade:

To confirm the correct cid for the AMC V-8 the cid number is cast on the sides of the block in approximately 2" high numbers, they’re located behind (above) the engine mounts.

For Ford BB casting numbers try : Gear Head Racing (http://www.gearheadracing.com/RefLibrary/BlockCasting/BigBlockFordCastingNumbers.htm)

I recently found out the deal with AMC stamping in the cubic inches of the block on the block in big numbers, and i found out the 390 is not a 390 but a 360, would this change the tranny?

Hi, it looks like you may have a 727 on the 360... to check look at the carb linkage. You will find a lever and rod assembly that will go behind head and down to the tranny. The 727 is a good option since the BW's are weak. To bad about the 360, but you do still have dogleg ports on the heads... which will be a lot better than the 67-69 343 and 390.

Look on www.rockauto.com They have a conversion kit for my 68 Ambassador so it wouldn't surprise me if they have one for you.

I believe that all big body cars share the same spindles. So you can use disc brakes from later year Matadors and Ambo's. If that 360 is a '70 or '71 you would have a Borg Warner trans. The internals are very similar to the Ford FMX.
