Another fine choice is the 385 series 370 cube Lima engine. They don't get mileage worth snot, but they pull like a ***** in church.
If it feels healthy, I'd have total faith in the trans under you, if your worried, drop the pan. It would give you a chance to check to look for shavings and such anyway, I've heard anything more than a tablespoon is a rebuild is a good rule of thumb.

A 460 based Ford heavy duty truck motor, dummy. lol
i more worry about what the other half will put it thru! LOL especially if i do the 426.
Just make sure it shift's firm. If your willing to let the other half loose with a 426, I'm sure she knows how to put in in (D)... No OD in the city/towing!!!!
thus the heavy duty planetaries and extra clutches!
...that come stock in the 46.
If you decide to tear into it, do enlarge the the last 3 feed holes, OD feed, in the output shaft by 30%, add the 2.74/1.54 gear set from a 42RH, a you can get them from wittrans.com, I love those people, they will give you good discounts if you tell them your a shop.
Enjoy!
