71 Dart get 408/ Trick Flow Heads....

Ok....bolted the Super Victor on to the engine....got one bolt I can not get a wrench on ...using 12 pt heads and it will not work on that bolt hole...got plenty of time to get one bolt..
I had to grind on that super victor to make room for bolts and distributor to fit. So test fit it as well as the valve covers. Had to clearance them as well.
