Something told me you were gonna throw in the "Well all I added to my engine
was..." deal.
I was comparing stock numbers. In previous statements, I also said that when
compared with at least the 318 ( I know, diff. engine, but I have no basis for
this with the 4.7L yet) that the same mods on both engines will produce far
better results on the 5.9. I would *guess* the same would be true with the 4.7,
but I may be wrong.
If you want to compare apples-to-apples, and you want to use your truck with
your mods, then you need to compare it to a 5.9 with the same exact mods and the
same exact mileage. Since you will never find a 5.9 with the same exact mods,
and the same exact mileage, you can only rely on the stock engine ratings for a
base comparison.
So again, yes, the 5.9L only posts a HP diff. of 15HP, but the STOCK ENGINE
shows a gain of 50lb-ft of torque. In my book, 50 lb-ft of torque is a world of
difference. Hell, I wouldn't care if the HP rating was the same. That is one
problem with the smaller displacement engines that everyone is going to; They
can make lots of HP at a high-RPM, but they fall short when you look at the
Torque numbers. I say that if I race you, and if you have more HP, but I have
more torque, then the race is mine.
So Matt, and don't take this like I am talking another truck down, but there is
a *15* HP diff. from the 4.7 to the 5.9, and a *50* lb-ft of torque diff., not
10 HP and 10-20 lb-ft.
