1971 EV2 Dodge Demon "Sizzler"

I am thinking of cleaning up the bock and putting it away for a future full resto. I have an extra 318, as well as the 340 and 360 sitting around, I MIGHT just put one of those in and have fun with the car for a while while I do other stuff to get it restored. Doing a RESTO, I'd love to find what it came with from the factory. Is there any way to get a hold of build sheets? I've never wanted to restore a car I had before, so, this is kinda new to me.
