i had a 4bbl and TBI 454. The TBI was a bit better than the 4bbl, even tho both had 235/385 specs. Issue both had the POS TH400 trans behind them. Too tall of gears in fist. Stalled them out on mid teen to 20% grades quite frequently, blew up trannys every 30K like clockwork, even with 6K fluid and 12K complete flushes including the TC.
Im probably not too far from you in Brier by the middle school. There are a couple of dozies coming up here from the east to west too!
