I have the same motor you desire in my 71 t. If you are going to run pump gas the general opinion from the many experts I consulted is to keep the CR under 9.5. I hope others chime in here but mine is under 9.5 and I run Pump gas. Another tidbit, based on the many drivers I consulted, I switched to Chevron (I am in California) and it does run better than the 76 I ran before. If you build that motor you are gonna love it.
