Agreed. My 327 is out of a '66 station wagon, and bolted right into my '65 C10 where the L6 was. Clutch pivot mount, motor mounts, exhaust routing were easily addressed. There are lots of options for accessories and drives...I like the look of those new-fangled serpentine systems with the billet aluminum pulleys and brackets.
Good luck.

If you can't fix it with a hammer and screwdriver, you need a bigger hammer.
