#57297 03/06/2006 2:21 PM | Joined: Dec 2002 Posts: 127 Wrench Fetcher | | Wrench Fetcher Joined: Dec 2002 Posts: 127 | I have a 1954 chevy truck with a 235 in it. I am going to be putting in a new cam. I was wondering what the easiest way to install the cam would be? Is it possible to leave the engine mounted in the truck and replace the cam or should i pull the engine and do it? Also what is the easiest procedure on replacing the cam? I am doing this for the first time and do not want to screw something up. Any help would be great, Thanks!!! | | |

I have pulled the cam on these motors before, mostly to change the timing gear. | | |

Yes you can replace the cam with the engine in the vehicle. You will have to remove the grill and radiator from your truck in order to remove the cam. As an alternative to removing the grill and the radiator you might want to consider pulling the engine to replace the cam.
It is sort of a toss-up as to which method you choose to use. It is much more easier to work on the engine when it is pulled from the vehicle and mounted on a stand. However, it takes just about as long to pull an engine as it does to remove the grill and radiator.
Just take your time and follow the procedure in the shop manual.
Good Luck,
Jon
P.S.
If you block has not been modified so you can remove the timing cover without removing the oil pan you will have to drop the oil pan to get at the two timing cover bolts located inside the oil pan. I learned this the hard way when I was an impatient rookie replacing the camshaft on a 216. | | |

There is a suggested position for the cam to be in. If you get the cam in the wrong position, it can hang up coming out. You also need to support it properly so as not to damage a cam bearing. | | |
