There is definitely something wrong. My Dakota that's in my sig is 3840 lbs and has a 2.94 gear. I have less cam and ported stock heads also. Your only 4 mph faster. Has the engine been opened up recently? Have any parts been changed?
I bolted the heads on about 6 years ago and ran it with the stock cam, about a year ago i installed the cam and converter but the engine hasnt really ran much. i work 60+ hours a week and i just recently started playing with it again. this is one of my 4 cars. 3 of which are toys so it gets neglected for months at a time
