Is there any value in a 3 speed manual trans?

Were going to try to grab two more truckloads on Wednesday. I will grab the trans and post a pic. These loads will be mostly engines and transmissions. A couple 440's, 2 383 blocks, std bore 340 block and many many heads and intakes. Its going to be a heavy load.
I did score an E body and an A body 833 the other day plus several bellhousings including a lakewood.
I guess I was hoping the tailshaft would work on an 833 so I could convert one to A body. I have a pile of B/E body 833's.
