K-Member Question 66 Belvedere

[BB BELLA]

Don't worry, the K-Member isn't the issue here. All V8 K-members from '66 to '70 are identical, doesn't matter if it was a 273 or a 440.

it would make a difference if his 273 was installed onto a slant k member with shumaker mounts is why i asked if the motor was original!

The difference is the improved idler arm mount, introduced in 1968. Other than that, they are functionally the same.

 

[BLK 68 R/T]

I heard that as well, but where are the differences?

The sway bar mounting is different in 1970 and later. Hemi uses its own unique design for the motor mounts.

Early '66 also had different sway bar mounting. But we are getting away from the fact that the V-8 crossmember will accommodate anything from 273 to 440, with exception of 426 Hemi which had its own distinct crossmember.

Strictly speaking from a motor exchange standpoint, yes. But just buying some random k member and bolting your engine in may be all fine and dandy until you go to install everything else. So it’s important to know what you need and what you are getting. Blanket statements (not by you) that say all 66-70 b body k members are identical is leading people astray.

To clear things up here, i need to mount the bracket from the front side of the block. Dont know why, but thats the way the engine is in now and sits correct in the bay

 

[Diewilde13]

Here you see. On this way it fits.

 

[RemCharger]

Well, that's not the way it works. Something must be fighting you with the other 2 drivetrain mounts. Assuming it's bolted to the trans.
I would disconnect the left and rear mounts, and see if the right side will go together properly

 

[mattsmopars]

I would think either the mounts are made wrong or you have the left bracket on the rt side and the rt side on the left setting the engine back. I saw you mentioned originally you had a 904 trans that will also need to be changed out to a 727 for a BB application and will require a different driveshaft.
