If the engine checks out (tight) not too much. Cam, intake, carb and exhaust.

I just rebuilt my mark IV 454mag to 461ci 9.4:1 comp.
Only thing I left was the block, crank and conn. rods.
All else is new.
560hp/550lb torque.
But i'd still rather have more cubes.

How much you wanna spend.
And there is much discussion on this in the Tech Q&A section.

Sorry... just re-read "bolt on".
Bolt on a charger and exhaust or save your $.
