alright, THIS DOESNT LEAVE THIS THREAD, but I had an F150 in high school with a 3spd + overdrive and a really tall rear, and I had the same problem...you couldn't get teh clutch all the way out until like 10 mph...it was miserable. If I had kept that truck(?) I definitely would have put either a 5 speed, a granny 4 speed, or a 4.55 rear in it. For your truck I would put the SM420 or 465 in like the others are saying. $.02, thank you, come again.
