360 build suggestion

This car has been built from the back forward. 8.75 sure grip, 489 with 3.91`s. Rock solid 904 with reverse valve body. SS springs, CE shocks front and back, sub-frame connectors. All we need is a budget 360 to install in it. I have the `72 block 360 in my garage. Picked it up complete with a 727 for $50.00. With 4 kids in college, I have no other choice than to do a budget build.
