I have 1990 Thunderbird, it has the original 3.8L, I would like to put a bigger motor, or anything with a little bit More HP, could some point me in the right direction? What size of engine, and what year of engine? I have a 1989 LTD crown Vic, that has low miles on it, which has the 5.0, it's a complete car that has a salvaged title.
