Follow up: It's been 800 miles since the above. I had the first opportunity to tow my 6,000 lbs of Jeep+trailer yesterday with the new roller rockers and the head work. Wow, the motor is a LOT more comfortable in the mid-range (3,000 ROM at 70 MPH with OD off). It takes a lot less right pedal to manage speed on the usual slight hills on the Interstate.

Anyone thinking of the Harland Sharp rockers... go for it!

 

Good to hear. My new to me 98 ram has 3.55s and could use some help. Definitely a big adjustment from my durango with 3.92s and I contemplated the harland sharps in that.

 

oooooops wrong place
