I have searched and read a reasonable amount, but I am curious as to the consensus regarding rod bearing oil clearance on the L6. I have encountered various different ranges from the different sources:
"rule of thumb" 0.001 per inch diameter
FSM materials (1972 = 0.0006 - 0.0022, 1982 = 0.0009 - 0.0026)
"how to modify" book 0.0023 - 0.0028
an engine builder to whom I have spoken said 0.0015 (regardless of diameter)
I was looking to target 0.002, and I currently have 0.0023 - 0.0027. I am concerned that I am potentially too loose. This is for an l28et rebuild with stock rods targeting ~300whp. So, for the L6, what is a recommended rod bearing oil clearance for such an application?
