As I said in a the cam card thread, turning the crank takes 35 ft-lbs for break away and 30 or so to turn. And there is more grim in the cylinders that I like so I pulled the pistons and rods out. Almost all of the pistons have dirt completely around the outside above the top rings. THe bearings have a date of 2021 on them so the short block was not assembled before that. I was told it was done in the 2018 time frame.
THe crank spins easily with only the cam and timing chain installed; 10 inch pounds for break away.
My questions are what is the torque for the rod bolts; they are labeled SCAT 44 ARP 8740. Also what should I use for lube? They have a light coat of moly on them but it looks dry.
Someone, Blair maybe, told me that these bolts should be upgraded if I was going to do some serious racing. That is my plan so what should I buy? Years ago, a bolt change required a resizing of the rod is that still true?
