If your 6X heads are original to the motor then its a 1976, but either way if you have -4 type heads then your compression is only a meager 7.6.
In that case a Sum-2800-1 is the cam I would use+ it’s lift will work better with your stock valve springs.
You will of course need new lifters and timing chain and gears.
You will need to remove the radiator to get the old cam out and the new one in.
It will the help of a second person to guide the old cam out and the new one in without harming the cam bearings.
