Cab brings up a good point about the converter. I have struggled with getting a good street friendly converter. Most just aren't good street converters given the torque our strokers produce.

Lenny at Ultimate finally put one together for me that is tight enough for a mostly street car.

One thing to keep in mind is that when we upgrade to one of these 500+" torque monsters, almost everything under the car will have to be considered and possibly upgraded to handle the massive change.
