Help with 413 Build please

Please post more as you go on with this as I would love to see what you do here. I am building what I hope will be a low buck car from a 70 dart swinger with my 16 year old son. I started with pulling the car out of a field where it had set over 20 years, paid $250 for it. took our time making our own replacement floor pan patches as we waited to see if we could get a title. We now have the title in hand and think leaving the stock 198 /6 out is a good idea, we have a 413 out of a 65 300. It is a replacement block with 68 date code and little other markings. It has been sitting for nearly 30 years full of drain oil and turns by hand, so we think it will be usable. I have heard many say to just use a 383, 400, 440 etc, but like some of the other guys said here, there is something sexy about the 413! Please do keep us informed.

Thanks
