My 84 has a 3.8 l V6 and I have an opportunity to get the intake, cam, heads, and computer out of a mid 90's F150 with a 4.2 L V6 for free. I am just wondering if these parts would work, or if the 3.8 and 4.2 are just too different to use parts between them. I am probably crazy for even attempting this, but lemme know.
