If you want to drive to Kenosha,Wi I have a 727 with 2500 convertor . I would go thru it but did do duty in a drag years ago. Has deeper pan and told internal upgrades but make no promises as to what as this was in a car I should never have bought and has turned into the SECOND dumbest thing I have ever done. $150 and take it away. I also have 2 904' with convertors that worked fine when removed. Not to kill a possible sale but with almost same work to a 904 as a 727 you will not hurt it with 4 to 500 hundred hp unless you just plain abuse the crap out of it. Good Luck with the project
