Now we can see if we get to the meat of things..
The holley lower was designed after the ford truck lower..
It will not work with the stock ford upper.
It is a kit with upper and lower from holley...
If you want to keep the stealth look I would just do some port work.
The truck upper has the throttle body on the wrong side.
I had thought about doing that but the throttle cable was on the wrong side..
Let me know what else you have questions on if I can help!
