Ok here's my delima, if you wanna call it that... I have the itch to purchase a second Mustang namely an 85-86 GT or 87-93 LX 5.0 Notch, but I would also like to make the 98 I currently have quicker. So here's my question should a leave the 98 as is, minus the 4.10s it's gonna get regardless, and get one of the above mentioned Foxes and focus my need for speed efforts there as they are lighter and the 5.0 is cheaper to mod, or shell out the dough to make the 98 quicker.
