Howdy, new to this great forum. I have the option of purchasing a 1998 Chevrolet Cheyenne 3500 2WD flatbed stake truck with 56K miles and 5.7L or a 1998 GMC flatbed stake truck with 93K miles and 7.4L. The lower miles on the Cheyenne is a big plus. But I not sure of the power loss between the 5.7 vice the 7.4. Everything that I have read seem to indicate pretty similar motors. Your thoughts and recommendations are appreciated...........

Depends on what you want to use it for... the 5.7L will get is behind kicked when you have a full load or towing a full load compared to the 7.4L however the 5.7L is going to give you better milage unloaded. the 7.4L will give you about 11-13 and the 5.7L will give you 12-15ish. If you want to tow, and work the truck i honestly would go with the 7.4L since you will never run it out of power.

I am looking into the same type of purchase and am also considering the differences between the motors. The 7.4 is a big block and will have a lot more torque for if you plan to do any significant amount of towing, but from my research it will come at a loss of gas mileage. If you are planning on just loading up the truck you will probably get by with the 5.7 but if you plan on trailering often I would personally lean toward the higher torque 7.4

Thanx Guys. I decided to buy the 5.7. Will not be doing much towing and will be used more of a work truck hauling material, yard debris, etc. The 5.7 model had new tires, a heavy duty hitch and overall better shape. The 7.4 model had bald tires and no hitch and the 93K. Appreciate your advice and quick response, thanx..........
