I'd go new. Why? less hassle with machining issues, and old age. 455
blocks, heads and cranks are readily available from aftermarket suppliers.
I'd rather have new hardware underhood than something of questionable
rebuild able quality. Granted, its your vehicle, but I'd rather err on the
side of something I can depend on.

As for performance improvement, Edelbrock makes aluminum manifolds, carbs
intakes/exhausts, basically an entire "power package" for the 455.
