I'm really considering doing it this winter. I don't really think much will have to change other than the tranny mount and driveshaft length. But I have no clue where the shifter lines up with the hole in the car with my engine placement you know? It would be nice to get the engine a little farther back so I can run a stock hood without a scoop but oh well.
Oh, and it is stock internals for now. I would really like to do a cam and heads, but I haven't looked into it too much yet.
There's no replacement for displacement.
