My 70 Duster build

I appreciate the work involved and getting your family involved in the project....cudos to you.
However, why would you take a step back on horsepower to 275-300 when a slightly warmed over 360 would get you there a lot easier?
Dare to be different? I like that and it's a cool looking engine and all....but why really?????
It's a cool swap though.
Interesting.......
I wouldn't attempt it though. To me it's backsliding.
What do you expect it to run? 15's at best is my estimate.
