  • there is no chance that anyone on this site has a slower truck than my 83 6.2 4x4 diesel...

    but yes, making the tow vehicle faster is the right thing to do

    • If this 5.2 ever dies, I may be tempted to put in a 5.9L or build a stroker 318 (4" crank + 318 = 390"). Sure would pull the trailer nicer. The 318 works ok, but could use a little more powah to eliminate shifting out of overdrive on long hills.

        Mr. Lohnes new purchase may give your diesel a run for it's money in the slow department. Too bad they are on opposite coasts and it would 2022 before the two vehicles could meet in the middle of the country if they left tomorrow.

        • BBR - "if"?!!! I have two words for you "power tow"

          Randal - lol; but to differentiate trucks his is slow for a purpose (as it's a medium duty work truck), mine is slow to make people smell it longer and give kids on bikes a chance to out run it (with streamers flapping in the breeze).

          • I saw a 6.2 suburban a couple weeks ago, driving down the freeway in Phx, black smoke spewing from both pipes. I was impressed that someone was still driving one

                  Randall, if you are even halfway serious about this, I can personally promise you that there is an easy 200lbs of insulation and carpet padding in that buick. Remove interior, remove "extra" crap from under interior (even scrape the bottom side of the carpet) reinstall interior; visually the appearance is the same. Its amazing how much weight is in all that deteriorating cushy stuff.

                  • As a fellow Durango owner I can say that an upgrade in HP would be a good thing, mine is a 4.7 OHC with all the tow package goodies and 3:90 gears. I’ve been disappointed with it since the first time I towed with it. Just not enough torque at towing RPM.
                    When I was pulling my Gremlin through the Virginia Mountains I was having dreams of a Diesel as the temp gauge would climb with the engine screaming in second at every steep climb… that and the fact that the salty winter roads have begun to win the rust war points to a new Larger tow truck in my future. If I lived in a rust-free area maybe more cubic Inches would be in the cards. How big can a small block Mopar go?
                    I hope to get 200,000 miles prior to its demise, at about 175,000 now.

                    • There is not much in the interior of the Silver Buick. I was warned about being scalped getting in it.

                        360 blocks can go 400+ inches. 318's can go 390+.

                        The first leg of my trip from Amarillo to OKC, when I did not have any wind or maybe a slight tail wind, it got 14 mpg dragging an 18 foot trailer (1500), Mustang (3300) and other stuff (400+). When I picked up a head wind, mileage went down to 10-11. It only had to downshift to second once when climbing a hill. Third was sufficient to maintain speed and even accelerate up most hills. I ran it with the overdrive on 99% of the time. It seemed happy to downshift by itself when necessary and then go back to o/d. This truck is a '98 and has the 235/75-15 tires, 3.55 gears and has 140k miles on the clock. If it had the optional 31-10.5's on it, I bet the 318 would have had a much much harder time. Coolant temps stayed under 210 (middle of the gauge) except for when the water pump disintegrated in Edmond, OK on the way back. lol

                        Overall, I was happy with how the truck performed. It could use more power or 3.92 gears, but I just don't tow this much stuff with it all that often so it will be ok for now. I was a little jealous of all the Dodges and Super Duty Fords that passed me on the highway though!

                        • The rear carpet piece is still in there, but the front carpet and insulation has been pulled out and is just some heat insulating bubble stuff with the rubber floor mats thrown ontop. The interior trim pieces and head liner are all removed.

                          • if you're going to race the durango - gas, but why spend all the money to bore, stroke and tune that motor when Dodge has an awesome diesel? for a tow rig, there just isn't a comparison. My 6.2 is slow, and plodding but there isn't a hill where 45mph is the slowest its going - okay, there isn't a slight incline where it isn't doing 45 but still - I'm getting 13 mpg towing 20,000 lbs and 25 empty.... with the cummins diesel, you get that same mileage and the ability to turn up the wick to where you'll need a full cage.

                              • couple of helper springs for that heavy muther of a Cummins... I got 14 pulling a fullsize Bronco behind the Lightning this weekend at 70, and I was thrilled. If traffic will hold 70, it doesn't downshift. If we get down to 60 or so, it will downshift going up hills near Temple. It's around 2300rpm at 70, so it's pretty happy there. (4.10 , .7 od, 30" tire)

                                I'd try the gears first.
