Sounds like you need to pull the oil pan, and check connecting rods/main bearing caps for excess play, sounds like a spun connecting rod bearing, giving that banging noise is the connecting rod being smacked around on the crankshaft.
Back in the early 80's a friend and I went through 3 short blocks in his 67 Camaro from Friday night through Sunday night, we had swapping engines down to a science, with each successive engine ending in a glorious loud final bang and a connecting rod (or remains of one) hanging though the side of another SBC (283's) or through the oil pan... yeah, I've hear that banging sound before
