If it was a Cerbera it would have been either a 4.2 (AJP) flat plane V8, a later 4.5 version of that engine, or 4 litre 'Speed 6' version...minimum 360bhp....max 420bhp.
The only TVRs that came with a 3 litre (Ford 'Essex' V6) were the Taimars, 'M' series and 3000S, which were all 1970s cars.
The first Cerberas were produced in 1995/96.
