1970 own owner orange 318 car super nice

Does it have an 8 3/4 rear? If so, what gears?
It might be worth it to change the cam to a 9/16, the 3/4 cams are barely streetable unless the compression ratio is about 11.23:1 or more from research i've done.
What is the actual compression ratio? Are the heads 318 ones?
Does the carb hit the hood with the 7'' hi rise?
Can't wait for the pics.
