The Silverstone Classic could host the biggest collective grid of Historic F2 cars after over 50 entries have been received for the Historic Formula 2 FIA International Series races.
The HSCC - which runs the event and championship - has already taken 53 entries for the pair of races at the July 26-28 event.
The anticipated capacity grid of 54 cars should far surpass any previous grid of Formula 2 and Formula Atlantic single-seaters from the late 1960s and 1970s.
The Silverstone Classic entry includes drivers from the UK, France, Germany, Switzerland, US, Holland and Australia.
Many cars with significant histories will be on the grid including the ex-Emerson Fittipaldi Lotus 69, ex-Eddie Cheever and Clay Regazzoni Ralt RT1s, the ex-Wheatcroft Racing Chevron B29, the ex-Derek Bell Brabham BT30 and the ex-Giacomo Agostini Chevron B42.
A host of front-runners will be on the Silverstone grid, notably Darwin Smith in a March 722, Andrew Smith in a March 742, Neil Fowler, Martin Stretton and Matt Wrigley (March 782s), the Chevron B42 of Michael Wrigley and Matthew Watts in his March 772.
At least 14 of the drivers due on the grid will have previous experience in Historic Formula One, with both Stretton and Michael Wrigley being former Historic F1 champions.
Andy Dee-Crowne, CEO of the HSCC said: "Historic Formula 2 is experiencing a massive boom and the grid for the Silverstone Classic is set to smash all records.
"The cars look and sound fantastic and to see more than 50 of these cars on one grid will be amazing.
"Lots of people have worked very hard to build the championship to where it is now."
The Historic Formula 2 series is heading to Hockenheim this weekend and has 30 entries for a maximum grid of 37.
The second event of the season at Brands Hatch on May 25/26 is also filling fast with 25 of the 38 available places now taken.
