2003 F-150 Harley Davidson engine
I have a 2003 F-150 Harley Davidson model.
I talked to a very good Ford mechanic that specializes in hot rod trucks and he said that the Harley model did not have the same internal engine parts as the Lightning of that year. He specifically said the pistons were cast and could not take much more boost or HP increase. I had always thought the engines (HD vs. Lightning) were the same with just different blower pulleys.
I would sure like to get another 100 HP. My neighbor with his bone stock ecoboost with 3 people in it can dust me. What can I do that will not destroy the motor? Am I better off building this or purchasing a crate motor?
Thanks

Funny you should ask this, Todd. Just a couple place setting down on the thread list is the exact same question.
Here is the question and my response:
The internals are exactly the same, Todd. No offense, but your "very good Ford mechanic" is completely wrong. It's actually kind of sad a Ford mechanic can't get this right.

Here is the question and my response:
I just sold my 2004 Lightning (mistake) and purchased a 2003 150 HD model. I had hoped to change the pulley and get back to Lightning HP only to be told the HD model is not the same engine as the Lightning. I was told the HD does not have good pistons rods or crank like the Lightning.
Is it true?
