Budget 383 build - opinions needed

Several years ago I picked up a ’68 383 long block. I bought it from a friend of a friend who said it was running when pulled. It is a 9.2:1 2bbl motor. I disassembled it last year thinking I would do a total rebuild (my first ever). I have the resources to do this, but financially things have changed a little.
My questions to you more experienced Mopar heads;
What would be the minimum I would need to do to get this motor back together and running? I regret pulling it apart since it looked GOOD during disassembly. The goal is to swap this motor in my Scamp. I have included some pics - if they help with your answer. Could I re-ring the pistons and install all new bearings and freeze plugs and reassemble. Am I crazy?
Another option would be to rebuild the bottom end with new pistons, balance the factory rods and use the 906 heads as is. Please help me decide, and keep in mind I want this to be a stock build @300hp to install in my Scamp and have fun. Rather than post the pics again, here's the link to my FBBO thread....
