70 Cuda: Is there different K-frame for small block and big block?

[nakita7]

What's the scoop on K-frames?

[cudahob]

Small blocks and Big blocks are the same, 440+6 have skid plates.
6 cylinder and Hemi are different.

What is the difference on a hemi k member??

[Chryco Psycho]

using the 440 mount would block the #1&2 exhaust port so the mounting was revised for the hemi requiring a different K frame & mount system

I thought small and big blocks were the same, so they are different part number, meaning totally different pieces? Can't bolt a big block into a 318 car?

[Chryco Psycho]

the part # is different but both the small block & big block will bolt onto either

Thanks for all you help guys!

I put a 440 in a 340 Cuda. Just use the 383-440 motor mount brackets. I just sold two sets on ebay.
