What do you guys think? What do you use and what experiance have you had between the two. I will start off with our experiance. We have had 4 fords in a row that the motors started giving us major trouble around 60,000 miles. All of them were oil pressure problems. 2 of which were inline 6 300c.i. motors, 1 was a 302 and 1 was a 351. Out of those 3 motors the 300 had the most pulling power because of the long stroke and torque but even that motor was weak. These were our work trucks. 1 of which had major brake problems that nobody, not even a ford engineere could figure out. I had to replace the pads every 2,000 to 5,000 miles. Now on to our family vehicals. The 1997 expedition we had with the 4.6 motor and tow package was soooooooooo weak it stopped dead in its tracks towing my race car up a small mountain to the race track. We only had it for 2 years because it was a lease. Now we have a 2002 expedition with the 5.4 and it has SLIGHTLY more power than the 4.6 but still is wayyyyyy underpowered. The 2002 has major electrical problems. 4X4 will kick in on dry pavement for no reason, it runs really rough at times, some control module keeps going out on it. Nobody can figure out whats wrong so we are about to get rid of it. That concludes my Ford experiance and now on to our Chevy experiance. 1998 3/4 ton chevy truck with the Vortec 350, 4X4, snow plow, heavy duty trailor tow package. We got it with 40,000 miles on it. 3 years later it has 102,000 miles on it. To date I have replaced the brakes once, 1 master cylinder, 1 starter and 1 alternator. Has way more towing power than any of the fords we have ever owned and not one bit of motor trouble. As a matter of fact I will be honest here and say that i only change the oil once every 8,000 to 10,000 miles with mobil 1. Tranny has never once been serviced and we use this truck to hell and back. Now our family vehical experiance. 2000 blazer ZR2 with off road package, V6, and trailor package. Was a 3 year lease. Had more power than the 302 and 351 but less towing power than the 300. After 35,000 miles we never had a single problem. Well needless to say when we get rid of the expedition we will be getting a Tahoe and someday down the road when the work truck needs a motor I will personaly rebuild it with a 383 stroker kit and port the heads. After all our really bad luck with fords we will likely never go back to ford again.
