I have a '98 Z28 Camaro with a handbuilt LS3 motor which was installed June 2010. I've been using Redline 10W40 & K&N oil filter after break-in but I've found that the local speed shop has stopped carrying that oil. In addition, the oil pressure needle on the gauge sometimes twitches, even after replacing the pressure sending unit. The oil pressure is typically above 40psi at idle, although it reported between 60 & 80 during a short trip a few days ago when the motor was cold.
I ran the RL oil because I intended to attend HPDE's and going back to autocross, but I never have... it's all been street driving in central Florida. I've read various recommendations of PU 5W30 and M1 5W30 but that it seemed to matter whether it was a C5/C6 or a F-body (weight?)... would those still be my fill of choice, or are there other recommendations?
main bearing clearance .0022-.0025
rod bearing clearance .0016-.0020
Thanks!
Jim
