A friend of mine has a ¾ ton 82 GMC diesel PU. I think the engine is a 6.2 liter. As I understand it, it was the second diesel engine GMC/Chev. put in their PUs. The first engine was a 5.9 gas engine that they converted to diesel. The 6,2 my friend has is supposed to be a true diesel. The above info. I got from people who know a lot more about these things than I do. That's more people than I care to count , even using a computer- get the picture. The engine was blown trying to pull a travel trailer out of the supposed path of Hurricane Rita. Would like put a diesel engine back in it, but that's expensive. Have been told that it's next to impossible to put one of the newer diesel engines because it would require a new electrical harness and maybe more because so much of the wiring goes to the dash and instrument panels of the newer trucks.. Jasper (engine manufacturer) sells an excellent rebuilt 6.2 diesel. Their specs say that the engine has 245 ft/lbs of torque at 1700 RPMs. They also sell 350s and 383s (gas engines) which would fit in the truck. The gas engines have 315 to 330 ft/lbs of torque BUT that's at 3300 RPMs (maybe 3000). This truck has a 6" lift kit, very large tires, automatic trans. and 4 wheel drive. The purpose of this truck is to go to the beach and to pull heavy loads. Unfortunately, Jasper doesn't have graphs that show the range of ft/lbs to RPMs of the gas engines. I'd like to know what kind of ft/lbs. they produce at low RPMs.Q#1 Does anybody here have access to this kind of stuff? My instinct tells me that the diesel is that way to go because of the pulling power. At the same time the gas engines are cheaper to buy and may give the truck a better top end. With a load 70 is hard to get. Without a load, it may not get better than 75. Also, this diesel doesn't have a turbo. I have been told that you really need to investigate closely your choice of turbos or you may just waste your money. Q#2 Will a tubro help the top end without taking away power at lower RPMs.? Will it help with pulling power?
Q#3 Would the gas engine be better than the diesel. I don't take gas or diesel fuel prices into consideration because the diesel fuel price seems to yo-yo from above gas to lower than gas.
Thanks for your help.
