I dont see how a 200 can "rob" you of more hp than a 350 th, you will be giving up a bunch of off the line jump by going from a 3.06 low gear (not to mentionthe n o.d.) to a puny 2.52 low gear in the 350th. Not quite as bad as the relationship of a 350th to a powerglide though, and thats an amazing difference- dont go with a 350 unless there's a lot of money involved.
