Rear end

[mopars]

Hey
I just got a 74 duster parts car and it has the big bolt pattern with discs and the V8 K frame that is all going to be put into the 67 dart. The quesiton i have is it has a 7 1/4 rear end with big bolt pattern? Im curious if these is going to be any good or will i have to keep on searching for a better rear end? The dart will have a 360 in it. Thanks

The 7 1/4 will not last with a 360 behind it. Look for an 8 1/4 or even better a 8 3/4.

I second that.

Thanks. Looks like i'll keep on searching. I"m also curious if i take the V8 K frame with all the steering will it all fit into the dart or do i need to swap out some of the part with the 67?

8 1/4 will handle up to 450-500 HP. they are more plentiful and cheaper than the 8 3/4 which is stronger.

If your asking if you can take the entire k-frame and all the pieces attached to it and put it in your 67 as a complete unit the answer is yes.

The 74 k frame uses spool type engine mounts which are better than the older biscuit style.That would be another bonus to using it.

Agree with the above on getting a bit stronger rear end in the car (no puns please!). Funnily though the '73 Dart parts car I had was a V8 car and had the 7.5 in it, but there you go. Lasting wise I thought it a bit too light for my uses and so built for the future as it were with an 8.25 swap. The 8.75's, although great, were just too pricey for my pocket.

See if you have a UPull it or Pick N Pull type scrap yard there. I wanted to upgrade the rear on or '71 Dart to large bolt pattern and a stronger rear and contacted a few places (Mopar yards). Got quoted anywhere from $350 to $500 for an 8.25 rear. Been seeing prices from individuals on them going up too it seems. Either feast or famine on them. On the opposite side I've seen people post to come get them for free, but will not ship. Of course, always half way around the world from where I am.

I went to the local self serve yard and found a '75 Scamp with one in. Pulled it out and ended up paying $100 for it if I remember right. Redid the brakes, popped the cover and checked the gears (3.21)/changed the fluid and swapped it in.
