360 swap 1965 Barracuda

Thanks for the info guys. As far as crate engines, does anyone here have advice about where to order from and where to stay away from, and whom has the best deals. I would prefer to spend less than 3500.00 on the engine alone. also what 8 3/4 rear will fit in my 1965 a-body Barracuda. and someone correct me if i'm wrong but when i look for the 4speed i need the one with the short tail shaft correct?
