ROLLER TIMING SET BLOCK CLEARANCE

ROLLER TIMING SET BLOCK CLEARANCE
When using a Double Roller timing set on a GM 350 Vortec or a GM K block, you must check the clearance between the cam gear and the bosses around the oil galleys in the block, Some blocks may need to have some grinding done for clearance and on some this was already done at the factory. An easy way to check is to place the cam gear on a camshaft then carefully install your cam into the block. Now just spin the gear and if you see it hitting the block just grind on the bosses until the gear has plenty of clearance. If not done, the gear will grind off metal filings that will be carried thru out the motor by the oil and we all know the damage this can cause.
