That's incredible but I hope they leave the 328 alone.

They really have no reason to touch the 328 as it wouldn't be period correct.

Here's an explanation of the car from QV500.com about the Group 4 cars. Later on, Michellotto also prepared 4 Group B spec 308s. The 288 GTO was to be the factory Group B car from Ferrari but in the same way as Porsche's 959, it never took off.


Ferrari’s series production 308 had never been conceptualised with motor sport in mind, however, a handful of interesting competition cars were produced and went onto compete successfully around Europe. Most were built up by Michelotto of Padova who not only received authorisation from the factory but also got a good deal of back door assistance. The machines prepared by Michelotto and Ferrari for racing fall into three categories, Group 4, Group B and GT/M cars. In addition, there were a few other competition 308 GTB’s modified by Facetti that we have also chosen to include in Part 8.


Ferrari homologated the 308 GTB back in January 1976 when the factory's Competition Department incorporated several competition spec components onto a hot experimental car. It included a specially prepared engine with high compression pistons, bigger carburettors, a four-outlet exhaust and a short shift gearbox with changeable ratios. In order to accept wider Campagnolo wheels of the type used by Lancia's Group 4 Stratos, there were also flared wheelarches. As the designation would suggest, the subsequent batch of Michelotto 308 GTB's were developed in order to comply with the FIA's Group 4 regulations. Ferrari supplied just the bare chassis's to Michelotto who immediately fitted a rollcage and adjustable roll bars. Weight was trimmed to just 1050kg, nearly 300kg lighter than the series production GTB. Engine-wise, displacement of the Tipo F106 motors remained the same at 2926cc, however, thanks to the use of Kugelfischer fuel-injection system and high compression pistons, output rose to 315bhp at 8000rpm. This power hike and the short shift gearbox with its adjustable close ratios meant these Group 4 308's were able to post some blistering acceleration times. Inside, they were pared down to the absolute minimum, being fabricated primarily from lightweight aluminium sheeting. There was a new flat top competition dash, the cabin being devoid of almost every luxury save for a pair of high backed bucket seats with safety harnesses. The bodywork was now a mixture of glassfibre and Kevlar panels with flared front and rear arches to accommodate the beautiful five spoke Campagnolo wheels. Other than these flares though, the bodywork of the Group 4 308 GTB's were identical in shape and proportion to those series production models. Just 11 of these fantastic machines were constructed by Michelotto (including one prototype), the chassis numbers of which are listed below:
