figured that was the case. so the price shown on the site "before checkout and options are selected" is actually before the core charge right?
dont get me wrong, i assumed that was what would happen. but seeing as how ive always built my own engines im not 100% familiar with the century long practice you speak of ;P

yeah its normal, and if you don't have a big azz cnc mill in your garage good luck sleeving it yourself. Pull your motor and send it to them.(or the whole car)
