One of ten “Hot-Rod” competition Daytona conversions built by Piet Roelofs in Holland. Each is built identically to the fifteen Factory built competition cars but with substantial engine, brake and suspension updates. 365 GTB/4C s/n 12681 features the same competition style modified plexiglass covered headlights, fender flairs and competition wheels as featured on the original Factory built cars. It also has the front fender air dams, front and rear spoilers, racing grille, lightened hood, outside fuel filler, rear brake scoops, engine cold air box, lightened doors and hood and trunk safety latches as used on the Series III Factory cars. The Daytona engine is virtually bulletproof, even in racing specifications, and the engine in s/n 12681 is updated with modern lightweight pistons, Carrillo rods and much improved cam profiles. Competition headers are fitted. The engine in 365 GTB/4C s/n 12681 features a fresh $31,510.70 rebuild by Ted Wenz’s Savannah Race Engineering with zero track time and produces 483 hp at a very-livable 7,700 RPM with 348 ft lbs of torque at 7,000 on the Superflow Dyno! Piet’s shop manufactures and has fitted one of their new and much stronger transaxle cases in 365 GTB/4C s/n 12681, while replacing the bearings, synchros and shift forks as needed while apart. A pair of the much stronger steel side plates was also installed. 365 GTB/4 C s/n 12681 is also fitted with the close ratio 4th and 5th gears.

As per later fax from Piet Roelofs:

“We had the engine on the Dyno and we’ve installed a short ring/pinion. Mr. Booker did two seasons of club racing at Zandvoort with this car. After this we have overhauled the engine and put Carrillo–rods in. It is 455 hp at 7800 RPM on the Superflow Dyno. Booker did only one race and some testing with this engine. The car has a rollcage, sprinkler, 90 liters fuel cell (2 years old), special AP front brakes, special shocks/springs, FIA racing seats, original cold airbox, special oil cooler and a twin master brake cylinder system, with adjustable front rear”.

1988, 14 Oct., in Holland. Registered on plate DE–22–91.

1995, Competizione conversion owned by Rudy Booker, NL. Red with black interior. Plates DE–22–91.

1995, Piet Roelofs converted the car in the spring of 1995 to further competition specs.

1996, 14–15 Sept., at a FCN Ferrari V12 Meeting, Zuid Limburg, the Netherlands. Race number 3.

1997, 29 Apr., at a FCN Driving Test at the circuit of Zolder, Belgium. This was the last time it was seen “in public”.

1999, 15 Feb., as per Piet Roelofs, this car is original plexiglas Daytona.

1999, 16 Feb., as per fax from Piet Roelofs the interior is black.

2000, 6 June, as per conversation with Piet the car is in his shop. The transaxle cases on Daytonas are the weakest link so Piet is installing one of his new and much stronger transaxle cases in the car and rebuilding the gears, synchros, etc while it’s apart. It will also have a pair of the much stronger steel side plates installed.

2000, 03 Aug., as per call from Piet Roelofs the car is still with Piet. It is not sold. It is getting the new and updated gearbox with the new stronger housing. So… the gearbox is new, new, new. It does not have the close ratio 4th and 5th gears. It does have the 8x43 rear gears, a very very short ratio gearbox. At 8,500 rpm they will do 250kms or about 145 mph.

The motor has only one race so it needs nothing. It is a very strong series III engine and needs nothing. The radiator is standard with a modified top tank. Has a separate oil cooler and they never have a problem with oil temperature.

It has the big “period” brakes, big roll bars, harder springs, the latest shocks, all the suspension updates, etc.…

The interior is a racing interior, but not “full race“. Yes, he has the original seats. They have new tan leather on them.

In Piet’s opinion the car needs, in principal, nothing. He thinks the wheels are new, but our client wants them painted. The paint on the car is good, but not perfect. For a racing car the paint is very good or even perfect.
