sixt8lou - I ran a WC T5 behind a mild 283 in my 66 with just the bell mounts, worked great.

ts71281 - good point, I was mostly replying to some of the info provided that mentioned using both, as in more is better. Yours is still a good question, and I'm not certain we've really answered it. I'm not certain which is the stronger setup - but Tim probably has a point here, on the higher hp arrangements, GM used the tailshaft crossmember. With a 468, hmmm.... that's kinda high hp! If it were me, and I wasn't sure HOW MUCH better the tailshaft mounting position was regarding handling hp - then I'd just stick with what I had. If you're planning any massive burnouts, perhaps might want to reconsider and move to the tailshaft approach(?)
