Good call 5.0HOTrain.... keep in mind also mcjc00 if your making any kind of power with that 351W your going to want to seriously consider swamping out that T5 for a Tremec or some kind of built trans (G-Force T5, Richmond, etc. etc.). The old T5 wont stand up to too much abuse from a high powered windsor. If it's in your budget I'd definetly invest in a good trans. to support all that power. If it's a mild 351W you can get away with the T5 for a while...
