i decided to go go to a 400 after pulling my motor apart its out of an 89 iroc...the only reason i pulled the motor was to fresh'n it up there isnt anything wrong with it and it should only need to be honed not bored out if wanted. The heads have crane h-11 springs and are included as well as the oil pan. It has a double roller comp timing set and a hot cam installed and the stock rockers/lifters/pushrods go with it as well. I live in richmond va and im looking to get 500 for the setup no intake though and yes its already disassembled
