Dear Dinosaur followers (all eight of you),
One question I often get at shows and on line concerns the differences between the Series I and II 500 Mondials. This post will endeavor to note as many of the differences as I recall.
Technically the Series I cars have a tipo 501 chassis and a tipo 110 motor, while the 2nd series cars have a tipo 510 chassis and a tipo 111 motor. The differences between both the chassis and motors are visibly stark. See first and second photos below for chassis comparison, and third and fourth photos for motor comparison. Not shown are the front suspension differences, tipo 501 has transverse leaf from suspension and the tipo 510 has fully independent coil spring front suspension. The tipo 110 motor is a direct descendent of the 1952/53 Formula car’s 500 motor with rounded cam covers and a narrow valve included angle, most often fitted with magnetos. The tipo 111 motor is a direct descendant of the 1954 tipo 553 formula I motor with flat cam covers and a wide included valve angle, always fitted with distributors. The dyno sheets for the tipo 110 motor run about 160 bhp at 6,500 to 6,700 rpm. The dyno sheets for the tipo 111 motor run about 170 to 172 bhp at 6,700 to 7,000 rpm.
All but five of the Series I cars have Pinin Farina bodies, those five have Scaglietti bodies with windscreens mounted on a flat cowl. All of the Series II cars are Scaglietti bodied and the windscreen is faired to the cowl. The Series I cars have 125 liter fuel tanks which results in a taper shape to the rear of the car (for the Scaglietti bodies). The Series II cars have 150 liter fuel tanks resulting in a fuller shape to the rear of the car.
The transmission in the Series I cars is a four speed tipo 501/279, while the Series II cars have a five speed transmission tipo 509/346 In both cases the transmissions are mated to ZF limited slip differentials with the resultant combination being a transaxle unit, hence the drive shaft runs between the clutch housing and the rear mounted transaxle.
A minor visible difference is on the tachometer face with the Series I reading 5, 10, 15, 20, 25 etc. and the Series II reading 10, 20, 30 etc., the red line is annotated on the Series II tachometer face at 7,000 rpm.
These are the many basic differences between the Series I cars and the series II cars. The 750 Monzas built in 1955 are identical to the Series II 500 Mondials except for the motor and tachometer face marking (the 750 tach red line is 6,000). In retrospect the Series II cars perhaps should have had a different name such as a 500 Monza, as they really have little in common with the Series I cars other than displacement.
