Hook 14,000 lbs to an F-250 and the first grade tells on the engine. The 7.3L Godzilla keeps it simple. Big gas V8. No turbo. No DEF tank. It makes 430 hp and 485 lb-ft, but it needs rpm when the trailer gets heavy. The 6.7L Power Stroke brings the pull. The High Output diesel … Read more
Bolt the EFI unit down, turn the key, and the pump whines longer than it should. Now the choice matters. Holley Sniper and FiTech can both make an old 4150-style V8 start cleaner and fuel better than a worn carb. Both can also stumble, surge, or die hot if the fuel pump, ground, O2 bung, … Read more
Park beside an R/T and a 392, and the badge starts the argument before the engine does. The 5.7 HEMI costs less, shows up in more cars and trucks, and usually asks less from the fuel pump. The 6.4 HEMI brings 392 cubic inches, Apache heads, and a harder midrange hit. In a Durango, that … Read more
Roll into the first long grade and the truck tells on itself. The 6.4 HEMI is the cheaper, lighter Ram HD engine. It burns gas, skips DEF, and keeps diesel filters and DPF trouble out of the truck. The 6.7 Cummins costs more, but its HO tune brings 1,075 lb-ft at 1,800 rpm. That torque … Read more
Hook up a camper. Watch the rear bumper drop. Hear the 62TE hunt for a gear. That’s where the Dodge Grand Caravan Tow Package matters. A 2011–2020 Grand Caravan can tow up to 3,600 lbs only with the right factory parts. A hitch alone does not make that rating real. Start with the build sheet. … Read more
Slide under the car and the swap points at one choice: cable or control box. The 700R4 keeps the job simple. It uses a governor and TV cable to shift. That cable also controls line pressure, so bad geometry can burn the 3-4 clutch fast. The 4L60E moves that work to solenoids, wiring, and a … Read more
Spot a clean 5.9 on steel wheels, then hear a newer 6.7 idle beside a loaded gooseneck. Now the choice gets expensive. The 5.9 Cummins gives you old-school diesel life, fewer emissions parts, and simpler repairs. The 6.7 Cummins gives you more torque, stronger towing manners, a VGT exhaust brake, and a heavier sensor bill. … Read more
Hook the camper, tap the throttle, and the smaller EcoBoost has to prove itself fast. The 2.7L feels right in a light F-150. It spools quick, sips less fuel empty, and makes errands feel easy. That’s why it works so well for commuting, family use, and lighter trailers. The 3.5L earns its keep when the … Read more
Spot the RPO code, then watch the seller lean on one word: 4L65E. That word can add money fast. The 4L60E and 4L65E share GM’s same basic 4-speed family, but the 4L65E brings the stronger LS-era parts, including five-pinion planetaries and tougher shafts. The 4L60E still fits stock trucks, mild 5.3 swaps, and budget daily … Read more
Hook 16,000 lbs to the hitch and watch the grade pull the truth out fast. The Duramax feels calmer. The Powerstroke hits harder. GM’s 6.6L L5P brings 470 hp, 975 lb-ft, a cast-iron block, and Denso HP4 fuel hardware. Ford’s 6.7L Powerstroke answers with up to 500 hp, 1,200 lb-ft, a CGI block, and a … Read more
