Hi all Im new here and impressed with the wealth of knowledge ive seen what im wondering has anyone swapped out k member from a 64 b body and replaced with a newer style i think this might simplify oil pan,headers and mounts that seem to be very specific for this vintage Thank you

Yes, it's been done quite a bit.

Gives better weight distribution along with, like you said, later header use, better engine mounts etc.

It does put the motor really close to the firewall, though.

Is tis a bolt in swap and about how far back does it move might be a shame because I finally found correct steering shaft to convert to manual but oh well Ive rebuilt everthing else on car not quite original any more

Just moves the mounts back. Yea it is bolt in. I did it on my '64 Fury that BobK has now. You can run the late headers and the oil pans fit as they would on a later car. A cross ram will not fit without "massaging" the firewall.

sorry for all these ? but i keep thinking of poss problems what about clutch linkage if I remember rigt not much room to move body pivot rearward

Also, you will have to modify the trans mount. Kevin did a great job on my (his) 64 Fury.

Thanks for all info guess I am on the hunt for old style headers this is gonna move shifter back to kinda hard with bench seat to bad Im stuck on making a sleeper but when the urge comes to build a true bracket car got some good ideas but for now I want to shift it any body have any input on stroked 383 Ive amassed some decent parts everyone ask why not 451 I guess I just gotta be different

Just some info for you in case you dont change the K-member. I still have the original K-member in my 63 and everything fits fine. I use Hedman headers and a Moroso 8 qt oil pan that fit with no mods. And I have plenty of room at the firewall. Weight distribution seems to be fine on my car. Ron

Here is the mount we modified when using the late K-Member. Basically moved the box back and down using 2x3 tubing. Was able to use a later A/B body trans mount from Rock Auto for $7 vs. the $79 one from Imperial Services.

We did it because I had two sets of headers that fit later B-bodies and no early B-Body mounts, so it was cheaper to just put in a $60 K-Frame that I got off ebag.

Engine sits pretty tight against the passenger side firewall. Modifying the kickdown linkage for an auto trans was a test in patience
