Oh im a huge fan of the 350 small block swap. But the td27t is upgradable, light and small enough to not have to do the sas, and hey,its diesel. Plus some states (va included) won't let you engine swap with an out of model engine if it's older than the model of the vehicle. If the engine says nissan on it you most likely won't have any problems. And did i mention the td27t is a diesel?
