K Frame ID?

[HotrodColt]

I am pretty sure it’s a small block k member from a ‘74 360 duster but I want to be sure, the transmission in this car is for a big block, not sure if the PO just installed the trans and never finished a swap or what, it also came with two 440s that were not installed. Tried to look up the part number stamped and came up empty handed, also thought it was weird to have the K backwards in the part number.

That could be a big block Direct Connection k-frame, but if not can be modified easily. Jim Lusk is the expert on those...

That’s what I’m hoping it is, but if not I am ready to modify it for the 440.

Looks like a base 73+ V8 K frame

It’s a small block K. If it was big block the rear mount ear would be back past the steering box mount. Kim
