70 MONTE Posted March 10, 2013 Share Posted March 10, 2013 Hey Guys, I'm looking to get New heads, intake, and cam. It's going in a stock 350 with 115,000 miles on it. My question is, can I just put the new cam in or should I change the cam bearings too? If I should change the bearings can I do that in car without removing pan and crank?

footballubet Posted March 10, 2013 Share Posted March 10, 2013 With that many miles they are probably due to be changed. If you replace them the engine would need to be removed. The rear cam bearing needs to be installed from the transmission side. The crank needs to be removed to line up the oil feed hole in the bearing that gets it's oil supplied from the crankshaft. This is the "snowball" effect! Quote Link to comment Share on other sites More sharing options...
70 MONTE Posted March 10, 2013 Author Share Posted March 10, 2013 Damn, I was afraid of that. At this point by the time you factor in all cost and trouble maybe it would be more cost effective and easier just to get a crate motor to drop in and keep the stock one.

footballubet Posted March 10, 2013 Share Posted March 10, 2013 The crate motor is a great deal. You can't beat them. Quote Link to comment Share on other sites More sharing options...
NewTimer Posted March 10, 2013 Share Posted March 10, 2013 When I re did my motor we spent about 3 grand, thats for parts and having the block and heads machined. Put it back together myself Quote Link to comment Share on other sites More sharing options...
wallaby Posted March 10, 2013 Share Posted March 10, 2013 With 115,000 miles on the motor, you're probably going to find out what the snowball is all about. I'll bet that you're going to find your timing chain is pretty much without teeth, and then the pan has to come off to clean them out of the bottom of the engine. Cam bearings aren't a high-wear item because the cam spins at 1/2 speed. You can probably change the cam without replacing them IMO, but you're going to find other things to fix and you should be prepared for a project. Often times a fresh valve job (new heads) will increase your compression and vacuum and you suddenly realize that your old piston rings aren't up to the task and the engine burns oil.
