You can just loosen the front oil pan but its a pain to work with. If the motor was rebuilt that recently and the springs were replaced then they should be alright. as far as pulling the rad see if you can hold the cam straight out agains the timing cover without touching rad itwould be possible. If it comes close to rad Your taking a risk. If it touches rad then rad has to come out. If its not a double roller timing chain I would replace it. Don't forget breakin lube and run engine 2500 to 3000 for twenty minutes then change oil.

The radiator has to be removed as well as any air cond equip.
I would recommend removing the oil pan to avoid having oil leaks because you did not want to take the time to take the pan off.
Fuel pump also has to be removed.
Just take your time and all will be well, you will swear with the radiator, but take your time.
You will thank yourself for removing the oil pan and doing it right. while you are at it put the 1 piece pan gasket on when you reassemble.

If You have never done this before, be carefull that You find out what springs You have and what the cam needs.Make sure You get Your distributor set pointing at #1 wire. mark the distributor position of housing to intake. Your balancer should be right at "0" on timing tab. Then when Your puting it back together make sure that #1 cylinder is on compression at the "0" mark. When You go to start it it will fire on first crank.

Just a tip to help reduce the frustration.
Don't forget to remove the mechanical fuel pump. You'll have to remove the pump so you can drop the fuel pump rod out of the way. If not the pump will push the rod up and it will catch on the cam and not allow it to slide out.
Yes, my first cam change this happened to me. After walking away a couple times I remembered the mechanical fuel pump......duh!
Good Luck!

The cam will have a spring requirement pressure wise. Take an intake and an exhaust spring at random and take them to a shop, have them check the spring pressure. You'll need the installed height. So after you have them removed, replace the retainers and keepers and measure the the distance from the spring seat to the retainer. (cover all holes leading into the engine, as one of the keepers will find it's way inside)
A cheaper way to give them the distance ould be to take a piece of welding rod or some other firm wire and clip it of a little at a time untill it is the exact length of that distance.
Or just buy the cam kit that comes with all the parts you'll need!!!!
