Krambo Posted August 26, 2006 Report Share Posted August 26, 2006 Unbelievable Don't forget about the 10MPG either. Sitll a cool truck though Link to comment Share on other sites More sharing options...
GotBoost Posted August 26, 2006 Report Share Posted August 26, 2006 They're nice trucks but damn they got shitty MPG. Anyways, that HP is about right if I remember correctly. It's due to some open chambed heads I believe. You could install a set of closed chamber heads and a cam to improve it some I'm sure. Link to comment Share on other sites More sharing options...
zippy Posted August 28, 2006 Report Share Posted August 28, 2006 As far as I know it was 235 for the first year. As a warning, lose the CAPS or you won't be posting on here. Link to comment Share on other sites More sharing options...
