Extra lobbying of car clubs and vehicle owners has left the organisers of Sunday's Fleetwood Transport Festival expecting more than twice as many vehicles as last year.
And they believe that this year's attendance by the public could be as much as 50,000.
The draw will be an exhibition of transport ranging from a hovercraft to a 1899 De Dion Bouton and possibly three DeLoreans.
Event chairman Keith Yates said that instead of having vehicles parallel to the pavement they would have to put some at 90 degrees just to fit them in.
Last year there were 130 exhibits but this year there have been 302 confirmed bookings so far.,
Mr Yates said a lot of the growth had been thanks to committee member Lawrence Weetman.
He said: "He has been harassing every single car club and anybody and everybody. He has spent an awful lot of time on Google and reading magazines to get phone numbers.
"An attendance of 40,000 is certainly possible and, depending on the weather, 50,000 isn't an unrealistic figure."
There are no admission charges to the festival so finances are a continuing problem. Mr Yates said that later this month the committee would publish a breakdown of the finances so the public could see where money went and what the main costs were.
He said: "In the past we have considered a main sponsor but they would take over completely and it would lose its identity and we would lose control.
"Once they moved on we could be left high and dry," he added.
Now in it's 24th year, the festival will be dedicated to the late Bolton steeplejack and steam transport enthusiast Fred Dibnah.
A statue of him was recently unveiled in Bolton and his widow, Sheila Dibnah, will be present at the event to talk to members of the public about Fred.
A former military hovercraft which will take small groups for a trip around the bay will be a first for the festival, although a test flight to satisfy the authorities will be needed on Saturday.
Also in attendance will be the country's last steam-powered bus and the UK's tallest limousine – a 16ft American truck that has been converted.
Blackpool Transport will be running a vintage tram service between the event and Blackpool's North Pier and one of them will be making its first public appearance after being refurbished to its original 1930s condition.
Owls and other birds of prey from the Owl and Bird of Prey Roadshow and the World Owl Trust will also be attending, and may be handled by the children visiting the event.
A gathering of town criers will be present at the festival, having competed at the national town crier's championships in Blackpool the day before.
The festival procession will begin a Fisherman's Walk at 11.30am.
