354 or 392? Hemi? Questions?

Ok so I realize it does fit and all and I know it weighs 750lbs but my car is only gonna be a fun street car not a race car.... I think it would be neat stock ratings are 280hp 380 torque. Not to shabby. Anyway here it goes... Do they make motor mounts for the swap, an headers? And a oil pan? If they do I might go this way I know it isn't a 426 but still a hemi would e a wow factor and still move a little Abody pretty good!!! If you have any info please let me know!!! Thanks alot!! I seen it done just not sure how... I can prolly weld up mounts but headers idk.... And oil pan idk... Please any help would be greatly appreciated
