Which Chrysler cars have a K member that fits a 72 Duster? What is all involved in doing a V-8 upgrade on a 6 cyl. Duster?

You may wanna check into shumacker mounts. Let you use you /6 k with v-8

This is their site.

I am not sure on a non spool mount k that you need to change the k itself. 73 spool ones yes, but the 73 may not need much done.

Also can post on www.moparts.org message forum.

I've done the 73 duster swap, but i had a doner 73 duster v-8 to use.

An issue I had, the Throttle cable is much longer on the slant -6 cars, using it on a v-8 will have alot of twists and turns and will probably bind some. My donor had poor one so I had to visit my local old car junk yard.

As for bolting in I think Any a-body one will bolt in. Dart, Demon, valiant, duster, scamp. 73- up have spool mounts 72 prior have flat plates. As I said confirm you actually need to change it out. You may be good.

SWEEEET I'll probably give them a call and possibly go that route since I don't even have to remove the K member. I seen on Ebay, the K members are selling for more than this kit THANKS M.J.

I bought a V8 K member out of a 73 Skamp about 1 1/2 weeks ago for $20 at a pick and pull junkyard. I have a 73 slant 6 Dart that I am going to put a 360 in but I wanted to go the cheaper route. The K member took me about 3 hours to pull out. The only thing left attached to it was the motor and the upper control arms. It was a pain in the......but for only $20 it was worth it.

Theres a guy that lives about 15 miles from me thats a HHHUUUUUGGGE Mopar freak. He has an old 2 story tobacco warehouse that's STUFFED, PILED, and CRAMMED with Mopar parts. If you can't find it there, they didn't make it. Anyway, he has a K member for this Duster that he'll sell me for $100.00 but I am still considering going with the upgrade kit so I don't have to F@*k with removing the K member. I wonder how well they fit. Anyone ever used them?

You need more than just the kit. You really should get some v-8 tortion bars also. If you use the /6 ones you will have to crank the snot out of them to get the lift, which is a bad thing.

On the shcumaker site they say this:

"These conversions greatly increase the power and add weight to the front of the vehicle (the B/RB adds 120 lbs. to the V8, for instance). You MUST upgrade your brakes for safe operation and torsion bars for better handling. A torque strap is recommended. Some vehicles have 9" drum brakes — these are not acceptable for these applications!"

Even with the k from they guy you know you should get the bars. If you get the k from that guy he may have bars, and as a bonus he may have some disc brakes (and proportioning valve and master cylinder)? Swapping the K and spindles is no harder than swapping the k alone.

Mopar Performance sells the torsion bars for A-bodies for around $125 you can also get them from Jegs, Summit Racing or PST. If your car is made after 1972, then you will have the larger brakes. The feds required larger front drums in 1973 and up on all domestic made cars. I would go with gettting a V8 K member, if you break one of those conversion mounts you will have to buy a new set to just replace one. If you break a stock motor mount on a V8 K frame you can get it at most parts store for under $20. The one thing that will definitely need to be changed is the rearend if you have the 7 1/4" under your car. It will work ok for normal driving, but to many burnouts with a V8 and you will send parts everywhere. I would look around, you can find a V8 K member cheaper than $100, I paid $20 for mine at a pick and pull junkyard.

I'm going to go look at the K memebr before I make a decision. I want the car to be safe.

Mine was easy, But i found a v-8 donor duster same year. After building a few dusters I had the donor stripped to nothing in less than 2 days. Left my house a shell of it's former self.

Does any of the steering have to be replaced or upgraded?
