I busted up the ringlands on my stock LS block today coming back from snowboarding, so unfortunately I have to install my built motor over the weekend. It is a B18C1 with 83MM GE Sleeves, 9:1 CP pistons, crower rods, ARP studs. Will the cold temperatures cause the motor to seize due to tight tolerances? What kind of oil should I run in this motor? Me and my Dad are going to swap it tomorrow and then trailer the car to a shop, break it in on the dyno and tune it.

EDIT: by cold temps I mean like -25, -30. I don't plan on boosting in cold weather, but I need transportation.

sorry this is alittle off topic but i saw someone else say "break it in on the dyno" what exaclty does this mean? also if the motor is BRAND NEW make sure you use non synthetic oil.

you break in the new motor on the dyno with the turbo while tuning

you should not have any problems. you should need more warmup time because of the greater piston to cyllinder wall clearance other than that it should be no different than a stock engine. i would recommend a 10-30 oil for break in. then 5-30 after that.
