it would be cheaper and easier to just get a used GT.

its more trouble than its worth to be honest.

Re: 5.4 or 5.0 swap on my 04 v6 mustang

I'd just rebuild the 3.8. Maybe stroke it to a 4.2 or something on those lines. Maybe even go as far as adding a power adder in addition to the built engine...then you'll be faster than a GT...

But that's if you want to keep the car. If you want a "faster" car with two more cylinders, I'd do as Wiarumas said and look into a v8.

Re: 5.4 or 5.0 swap on my 04 v6 mustang
