Which engine would you choose??

IMO do the most reliable swap. driving > wrenching and considering the age and intentions of the car, you're going to be spending alot of time on many other parts of the car and probably don't want to spend forever just trying to get it to move under it's own power. reliable may be the modern or the old swap...either way i think it would be the best choice. if you plan to keep the car long term you can always change your mind later if you want some exotic powerplant (thoughts of the 1JZ debacle come to mind).

also, 300hp is going to move that sumbitch down the road in a beastly manner. any amount of power over that would just be icing to me.

i'm also in the LSx boat but if you want to keep an inline engine in there you don't have too many places to turn.
