I have one, Its specs are inline 5 cyl. 2.5 liter , 20 valves ,170 hp. mine is a 5 sp. manual , most are Automatics.
Motor and tranny sit front to back Unlike most front drive cars .
So if you are thinking of a Swap , you will run into firewall clearence problems .
I think its only a single cam but not Sure.
try these links, the second one has more spec.
