I understand that when I send my LS engine away for some BOOST PREPPING, I want to make sure that when they cut the crankshaft, I wanna make sure they dont cut it down to much or else I will have to use aftermarket bearings. If somwhere could better explain this to me. It would help clarify what I should be asking the shop to do.

 

take it to a machine shop and ask them to micro polish and balance it. They will know what to do. COst about $200-300

 

Not to be out of place or anything, but i have an excellent condition LS crank for sale. CHEAP. The original OEM bearings werent even worn in all the way yet, really low miles.
