Bigmeanbaldguy Posted February 20, 2019 Share Posted February 20, 2019 I looking at a 2009 pinnacle with the MP8. Ive read that they have between 415 and 505 HP. however this one lists Max HP on the valve cover engine information plate as 338. the model is listed as a MP8-415c anyone know what this means? is it 338 HP or 415? the reason I’m asking is because it doesn’t feel nearly as powerful as my other trucks Quote Link to comment Share on other sites More sharing options...
