6T3 Nova,,,
I do not think there are any difference in the Nova's w/a six cylinder or a V-8 car frame.
Ask Twisted6, AKA Larry
So, up to a certain amount of HP & torque I would not worry too much about tweaking the frame.
Are you making a drag car? They put 300-or was it 350 HP?? 327's in the 66 Novas.
Only real time to worry about twisting the frame is when you have slicks,stick shift ,or auto trans w/a trans brake & so on.
Or you are auto crossing your car w/sticky tires getting crazy.
Then you would tie the front of the frame to the rear w/subframe connectors, run a cage & so forth.
A Hiedt's front end, would really be a great improvement on the Nova's.
More stability,holds alignments,+ strengthening.
