The 727 in my cuda is shot so now I need another tranny. I really hate to search for another 727 because I plan on putting a 518 tranny in a couple months. I have a stock 904 that I used behind a 318 for a while. Should it be able to hold up behind a mild 340 or am I wasting my time? 340 is stock 1970 motor with headers and hughes whiplash cam. I have the right driveshaft and everything for this swap so its not too big a deal.
