I used to have a 99 dodge ram extended cab with out all the power goodies. And before that i had a 97 dodge ram extended cab sport with all the good stuff. now here is the story my blazer is faster than both of these trucks and i dont know why. both dodges had 318 cids, 3.73 gears, 4speed autos, and both were same size, the 99 was lighter than the 97 and both trucks were lighter than the Blazer. Now my Blazer has a 305, 3.08 gearsand the 700R4 and it is 4WD, both of the Dodges were 2WD. Performance mods are as such: 99 Ram Flotech Terminator muffler K&N filter charger 97 Ram Flowmaster catback K&N filter charger computer module 85 Blazer Edelbrock carb Hedman headers Flowmaster mufflers Accel ignition dumped computer & emissions Also take into consideration the Blazer has 35x12.50 tires on it and both Rams had 265/70/R16 tires on them. Sorry so long but I had to just let you know how much those Rams suck. Probably the slowest vehicles I have ever owned.
