I remember my first car I ever bought. 1973 chevy vega. 70 series wheels on the front with 50 series on the rear. That engine was so bad that I actually found other working engines and trannys kept two of each on hand so I could change out the engine or tranny when they blew. I must of went through a dozen engine and at least two trannys in that car. I kept used oil in milk jugs in the back just to keep her topped off and running. I also got so good at engine changes that I could come home friday after school and change the engine out in time for my date that night.
That being said I have never had a vehicle like my orange crush ford edge that I have been able to put so many miles on. The work the manufacturers have done with engines today is hands down a display of engineering and fabrication process improvement examples that can not compare to the old days as they say. The manufacturers have learned a lot about aluminum and steel combinations that have opened up many doors.
Imagine having a Ford edge sport with the 2.7 back in 1973?! Nothing would beat it and people would be in awe.
