Interesting approach, but don't be surprised if you still have some issues to work through. I purchased a 66 and MP block package a few years ago. Getting ready for assembly. Been interesting working through the issues you find, unfortunately sequentially. Luckily, I have access to a mentor, and plenty of parts, tools and machinery and examples to work with. While major machine work, done at local shops, I got to deck my heads, and block, calculate all the specific blue print info. Was surprised to see how far off stock stuff was, but the mentor was not.
