Need help on a 5.4 swap
But Im here for some help if anyone can help me out with a few things ill greatly appreciate it.
Here is what I am doing!
Im swapping a 5.4 short block from a 3v truck (Has flat top pistons) W/ 4.6 P.I. head's from an 03 mustang GT.

My questions are:
1)What will my compression be with the set-up?
2)What intake manifold will work? I have this one and its a bit narrow
