engine swap help

I bought this 81 mercury zephyr, it is a 3speed auto and has a 3.3L 200 cid (inline 6). Thats got to go. i want to put either a 2.3L turbo from a 79-82 stang, If i cant get ahole of one of thous i'll just put a 5.0L in from 83-85 maybe 82. i know i will have to change the crossmembers, but how will i know if the tranny will line up and is here anything i dident mention that i should know? any tips would be greatly appreciated.

Why not just turbo the six? Anyway, I'm pretty sure any inline 6 after 69 has the same bolt pattern as the 5.0. Does that car have the 4 lug wheels? If it does, and you go with the 5.0 you need to swich over to 5 lug. Don't know a whole lot about the 2.3 so I can't comment.

Why would he need to swap to 5 lugs?

I might be wrong, I based that on the older 4 lug stuff. The 80's may have been stronger.

yeah, it has the 4 lug nuts, and i desided to go with the 5 0, more power, and i am just going to take the tranny out of where ever i get the engin from. but see i am only 16, first car, so i need al lthe help i can get.

hiflow, is that a b&m hammer shifter in your 89stang, if so, how is it? cause i am pretty sure i am gonna get that one.

Yup, it's the hammer! I like it a lot better then the stock one, looks and operation.

when i drop the 5.0L in, whats the best cost efficiant mods other than headers and exhaust that i can do to it to raise my h/p?
