K frame question from small block to big block

[GOTWING]

Is there a difference in a factory k frame on a 73 Charger thatcame with a small block 318 compared to one that came with a big block 440 ?The reason I ask is I have a big block parts car with a 400 and I have a 69 440TNT that I’m putting in my 73 and I wondered if they will need to be swappedout during the restoration or do I only have a difference in motor mounts.

Thanks !

Yes 73-8B has a different K-frame for BB and SB. 62-72 doesn't. Think the motor sits back further with a BB. The 73-8 spool motor mounting brackets will fit your 69 Block.
