I realize the temptation of using what you have and using an engine you know the history of.
However, for simplicity of installation, a 5.2 or 5.9 would be a more practical choice. From what I've seen/heard, 4.7s are decent engines but there is demand for used ones also.
The speed parts for a 4.7 will be very limited and very expensive.
Sell teh 4.7 and get a Maggie.
Parts I seek:
driver doorpanel, 65 Sport Fury, prefer black, needs to be 7-8 on 10 scale, might buy set
16" x 6" Dodge truck wheel(s), from early 70s?, takes 9" dogdish - need for a research job so cheaper is better.
69-73 C-body caliper brackets and/or splashields
