Alot say that a 350 Diesel is a Guttless Engine...Well my Big Bonneville has turned some heads!..I have towed mass amounts of vehicles of all sizes, from toyota to Buick..to monster 4X4 trucks with 36" tires...I pulled my Friends broken down Lifed 1979 Bronco that had a 21 foot flatbed trailer on back with a car on top down the highway for 30 miles at 60mph NO STRAIN!..Sound gutless?..nope..I dont see how..But the rag out days are over for me...gonna start treating it like a heavy slow car that its suppoesto be..not a big loud strong tow truck that it is capable of being.
