1974 Ferrari 365 GT4 B/B

yeah you're right. 3 links all with slightly different info. I seem to remember these getting less powerful until the testarossa came out.

the Lamborghini Countach LP400 from 1975 had a factory claimed topspeed of 305km/h... 9 years befor the 288 GTO

Thats wrong the first production car that reached(TESTED) 300km/h+ was a RUF BTR 3.4 (with small SC body) it was tested with 305km/h one year befor the 288 GTO hit the market.

There were several cars with a factory claim of 300km/h

The top speed must be wrong. The first car reached 300 km/h was the Ferrari 288 GTO

here is a good picture to see the differents a 365 GT4 BB from the side.. no spoiler no intake... like the car displayed on top..

The car gets different test numbers... even the power claims in the net range from 340, 360 up to 380hp and acceleration claims from 5.6 0-60 to over 6.3s 0-60mph to 7.3s 0-100km/h

Hard to say today which nubers are correct and which not

the car in the picture IS a 365 GT4 BB...

The 512 BB was optical identical to the 365 GT4 BB with 2 differents that you would see at this picture.. it was fitted with a smale spoiler lip at the front, a large intake in front of the rear tire ...

This 365 GT4 BB picture was taken during a auction in the USA...

This is a 512 BB with spoiler lip and intake infront of the rear tire..

I agree, stats are wrong as well.

Pictured blue car is not the 365 GT4... That would be a 512 BB

187mph for 340bhp from 1974???
