you will probably get lots of feedback on this, but here's my .02. The 292 will require some special mounts. You COULD make them, but I suggest buying from Tom Langdon at the Stovebolt engine company. These are superior mounts and work perfectly. The 292 is long, so you will need to either move your radiator forward or modify the firewall slightly. I did the firewall modification, but others have moved the radiator. As for your clutch, this will probably require some fabrication to get the linkage right. I chose hanging pedals with hydraulic clutch, so can't give any advice on that part. Most folks are swapping the rearend or at least the gears to get better highway speed. There are several options for this.......just do a search of this site and you will get lots of info.
good luck
