I recently found out that the piston rings in the origonal motor are going bad it is starting to smoke. I would like to put in the Other motor i have from a 1986 Ford Crown Victoria. I Know that the c4 4 speed wont bolt up to the new block, so i plan on getting a 5speed some time, but since i am going from a carb'd motor to a EFI setup, What i need to know is what am i going to need. I have the whole crown victoria still so i belive that i can still use the factory computer. But what else is there that i am going to need? Also with a new tranny, i dont belive that the driveshaft will be the same length that i need after the swap. Is there one from a different vehicle that i can use? Is it alot of crap to go through to put all of the electronics into the stang? OR is there a kit that is sold to make it easier to change it over? I think I have heard of one but not sure where. Thanx for all the help guys!
