Big Block Conversion, do it again?

I was honestly set on a 360 in my demon for exhaust purposes (easier to fit it) but my
Dad convinced me to go big block - plus I found a complete engine (2bbl core) for $175..

Have both size A727's and a B body 8 3/4 so it was up to just finding a cheaper magnum 360 or 383BB - found the BB after a 5 minute search and went the same day to pick it up..
