I have a 250/saginaw 3 speed right now in my 76 GMC. I have a 454 i want to drop in, but i doubt the 3 speed would last very long (especially how i drive it). An SM465 is a much stronger transmission, and since i'm on a pretty much shoestring budget right now, it fits the bill. I can get one for 50 bucks, but first I need to know what i would need to swap it in place of my 3 speed. Thanks.
