I have an 85 grand marquis that i got for free from this old man, it has a 302 that runs good but i got some money to burn and want to make it fast. i want to put 429 or a 460 but am wondering how much i could do it all for becuase i need a motor, a tranny and a rear, not sure if anythings else, so if anyone could help me out it would be much apprecitated
