That was the first thing my machinest ask is what WT oil was I using. I here people saying they run lighter

I've been running ,003 on my rods and .0032 or so also on my IA2, and that's all i use is 10/30, and i've spun it to 7500 a few times lol, never no issue when i've pulled the bearings,60 psi pump also
My stock block 468 we ran same clearances with 5/30 with different rods, now using molnar rods, its in the little details that make them live!
