I have a 92 f150 with a blown 5.0 and I will be swapping it out for another one I have, it is complete. Bother the truck and the spare engine are speed density and the truck has an e4od transmission. The question I have is this; I have an aftermarket can from my 79 302 mustang and it fairly aggressive would it be worth it to swap it in and will it affect the computer? Thanks for any help I'm new to efi and am enjoying learning about it.
