I posted stats from the sites of the two engines....
I'm a little confused though....
The GMC site called the torque comparison a GMC advantage...
Is 334@4500 more low down torque or 350@2500 more...

And could someone explain what is OHV???

OHV as the Chevy chart does mean overhead valve, but it is meant to also indicate the camshaft in still in the block, while the Ford lists SOHC for Single Overhead Camshaft.

I do have one question - If you're going to all the trouble to do an engine swap, why would you consider the 5.3 instead of the 6.0 when the engines are the exact same external dimensions, the electronics are the same, etc. For the money you spend it will SPANK your other options. Just my opinion.....

I wanted to compare the two... 5.3 is so much more closer to 5.4 than 6.0... lol
Besides, if I did a comparison of 5.4 vs 6.0... Surely the performance of the 6.0 will be better.

But I'm not just looking into performance.. I'm also looking into maintenance... I'm looking for issues with the engines that people have had with them.
I understand that there are quite a number of issues people have had with both engines.... But most issues seem to isolate themselves to their particular units, rather than the engine design.
I'm looking for the ones that hold on as actual design flaws... And I bet that even though there are fans of either engine, they will admit to something being a flaw in the engine's design.

Does anyone have an answer for the above question??.. This left me confused.... I always thought low down torque meant (more@less-rpm)
If that is true, then shouldn't the 5.4L Triton have the advantage??? 'Cos that's what the comparison chart shows...

Max torque at such a low RPM means this engine doesn't have a wide RPM range at all, rather like a diesel. It would mean choosing your gear ratio's very carefully as you don't want cruising RPM 500RPM past max torque. If you are always towning then that would be the better choice, but for everyday driving I would rather sacrafice a bit of lower range torque for a wider performance envelope and wider torque range. So the Triton would have a 16 lb.ft but the Vortec 5.3 would have more torque over a broader RPM range making it perform better overall.
