Didn’t you have a f-150 with a roush blower on it?
I’ve been looking at blowers for mine but leaning toward whipple over roush.
I kinda like this one better. My friend has this one and it seems to create more power with less boost.
Edelbrock F-150 E-Force Stage 1 Street Supercharger Kit T534361 (04-08 2WD 5.4L F-150)
Now if you don't care what it looks like and just want the most bang for your buck go with a pro charger...
Procharger F-150 High Output Intercooled Supercharger Kit w/ P-1SC-1 1FN211-SCI (04-08 5.4L F-150)
But yeah, to your original point....can't go wrong with a whipple....
