Personally.. I'm not a Ford Fan. (I like Chevy and Chrysler)
We had a discussion recently about the Ford Triton V-10 (Biggest) v/s the Chevy Vortec 8100 (Also the biggest)
The spec sheet shows the two are matched, foot pound for foot pound in the toruqe department. This is what gets you moving. The ford had 15 more HP (this is what keeps you moving)
What the spec sheet did not make clear is this
The Ford engine is a 'High-Reving" engine (I get to expierence this when I drive my wife's car) this means it does not develop full power, either HP or Torque till it's wound out some, quite a bit in fact. With my wife's car (a Mercury) Acceleration does not kick in till about 10 MPH.
The Chevy engine however is a lower reving engine, This means it hits both peaks sooner on the RPM curve, which means better performance "off the line" and a longer engine life
At the top end, the difference between 335 and 350 HP is .. Well, less than 5% and anything less than 10% is basically nothing... So I never notice the slightly lower HP of my Vortec over the Triton
And a hundred thousand miles or two down the road... I may well notice the longer life
(By the way, short engine life is EXACTLY the reason I'm not a Ford Fan)
