20 yr old day and night furnace short cycling

Hi,
I have an old Day and Night furnace that short cycles. It is an 80% efficient unit with a pilot. Always has done this and I have had techs out that told me the same thing my dad told me is that the furnace is to big for the house. He suggested speeding up the fan to keep the air box cooler/ Is this possible? If so how would it be accomplished?
