IMO, because if it's on a budget and staying with stock heads/intake/exhaust........ keeping those stock components and putting a longer arm in it would only make it more boring or, appropriate for a tow truck.


Stock 440 is already a lower rpm/torque engine.

If on a budget and you have a reciprocating assembly already, I would spend the money on head porting and cam upgrade long before keeping those stock and increasing displacement.
