Re: 5.3 vortec vs 5.4 triton

I have a 5.4 triton in a 1998 Ford F150

I like the engine except for a couple of things

spark plugs are PAIN to get to if you the DIY type. I am and I won't even touch them...
Exhaust manifold bolts rust and break leaving exhaust leaks. The night mare is if you have to replace the exhaust manifold, the studs brake and you have to bring out a welder to get them out.

Gas mileage 15 at best. I have never gotten it better then that. however I have an extended bed and long box.
It does tow very well


I would hope the 5.3 would be easier to work on.
