ok. ale to nie znaczy, że był dieslem ;) The Viper V10 is based on the rest of the LA family, and appeared with the Dodge Viper in 1992. It was conceived and prototyped as a Magnum 5.9 with two extra cylinders and a longer stroke of 3.88 in (99 mm). Originally designed as a truck engine[citation needed], Chrysler engineers revamped Dodge's cast-iron block V10 for the Viper[citation needed] by recasting the block and heads in aluminium alloy. Prototype blocks were cast by Lamborghini, at the time a Chrysler division. Some felt that the pushrod two-valve design, while adequate for the truck application for which the engine was originally created, was unsuitable for a performance car. However, Chrysler was uncertain about the Viper's production costs and sales potential[who?] and so declined to provide the budget for the modification[citation needed]. The first-generation Viper V10 engine has a displacement of 8.0 L (488 cu in) and produces 400 hp (298 kW) and 490 lb·ft (664 N·m).
