Re: wtk

I took a 305 out and bolted in a 454 with no problems. The motor came out of a suburban and I think I left the suburban mounts on the motor. I've done this swap on cars before with no modifications.

Re: wtk

as far as a 72 model, I don't know if the frame mounts interchange but I know if you put the existing 350 mounts on the 454, it will bolt up

Re: wtk

'72 big block mounts are unique to that year, only 72 big block mounts will work.
