K-member info.

[65post]

I have a 65 coronet post car ( sorry not a charger ) that came with a 6 cyl.from the factory and I have a 440 to go in it.My question to you all is will a later B body BB K-member bolt in ? or Thanks in advance to all who reply.

how much "later". Definitelly not 73/74.

Someone correct me if I'm wrong,  but I think any "B" body up until '70 will bolt up.   That being said...I do know that there are differences between a Hemi "K" member and a common "B"/"RB"  "K" member,  but I'm not sure about differences with a six cylinder though

The '66-'72 B body K-member will bolt into an early B but it sets the engine back 1 5/8" from the original position. This is an advantage for fan clearance, oil pan and header selection, etc. but it requires some fabrication and the floor tunnel will need some "massaging" for clearance. '68 and later have a better idler arm mount and '70 and later have a better sway bar mount.

Any '62-'65 V8 K-member will also mount the 440 with the correct mounts.

John, does the 66 - 72 K-frame set the motor higher as well?  Many years ago I set up a 65' Coronet with elephant ears at the stock hight, but moved the engine back. I don't remember having to modify the tranny tunnel..  Then again I cannot tell you if I had lunch today!!
