#99 LS1 CAM BEARINGS SERIES#

They fit the following LS series GM engines that use the 3rd design style cam bearings where the block housing bore on positions 1 and 5 measures 2.347' & bearing width is: 0.775'. Just wondered if anyone else has run into this and what you have used?Īlso found this on the standard Dura-Bond series: Guess I'll measure all the bearings and cam bearing journals to be positive. Started looking at the Dura-Bond with PTFE coating but they show one set for '97-'03 and one set for '03-'09. I was going to buy OEM GM bearings but all the GM outlets only show the iron block bearings for my model. I want to replace the cam bearings and thought it would be easy like most engines but have found different information in various places. Started tearing apart my '11 LC9 Aluminum block 5.3l so I can order parts. I'm new to the LS engine but not new to engine building.
