Back to the original post.
Stroker 390 (445) with Trick Flow heads.
500hp would be a breeze with 445 cubes and TFS heads.
One could also use a custom camshaft that would favor the exhaust - to lessen losses with cast 428CJ manifolds.
All in all 450hp should be easily attainable.

Would headers make more power? Of course.
Can OP make 450 Hp with 445 cubes, TFS heads and cast CJ exhaust manifolds? YES.
