Is this a big block K-member? W/ pics of motor/mounts?
The factory big block k-member needs a very rare mount for a 440 and a block that has holes drilled in the proper location.
Being a 67 k-member (requires an expensive idler arm), I'd recommend selling that to someone for a restoration and buying a 73-76 V8 k-member and making a DC k-member out of it...
