line bore

[92tsiawdguy]

I just got my block to the machine shop. They are boring the block for my new JE 87.5mm pistons and decking the block. They turned my 100mm crank .025 on the mains and .050 on the rods. i have a kiggly girdle and arp main studs. I know i need to line bore this block but i cant find bearings. If they take .025 off the line for the crank and you add in the .025 thats off the crank now, do i just use .050 main bearings? Thanks for the help

You will need the bearings to be over sized based on how much they cut the crank. When they line bore they will cut material off the FLAT part of the main caps and the block, where the two meet. Then they will bore the hole that they create back to factory specs.
