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

Has anyone fooled around with putting 392 pistons in a 354? I'd lil
Ke to get more power out ofba 354 and I was told that thatbwasbthe way to get it. Seems to me I'd loose comp. Thought about shaving the heads to get little more compression. If anyone has any ideas on what I can do letnme know please..maybe a good cam.. Specs???????

Thanks in advance
