When you replace camshafts, do u just take off all the pulleys and take out the radiator, or would u have to take the whole engine out and replace teh cam?

 

You have to take off the intake and carb/TPI, distributor, pulleys, power steering, alternator, radiator. I even had to bend the front cross bars a little to get the cam all the way out. It is possible with the motor in. If your cars has more than 100k miles, it might be a good idea to go ahead and replace the timing chain as well. And don't forget new lifters, probably a good idea.

 

Yep, just like Mark said.
I did mine 2 weeks ago and I helped a friend do his the next day.
Not really hard, just very time consuming.
