I would appreciate some help on opinions on 2 trucks I am looking at, 1 is a 2005 F150 V8 66000 miles. I here these can bend rods from leaky injectors? it's 7 grand and has a topper.

The other is a 2002 F 150 5.4 2 valve extenda cab with 80000 miles for 5500.

I hear the newer ones are better trucks but can have issues being 3 valve and can have more electrical problems. Any input would be great. Thanks.
