z6 crank vs b7 crank
 

i had a stock z6 that i had 9lbs of boost on for a couple years and didnt change the oil for bout 7-8000 miles and it developed a slight tap that sounded like a valve tap and ran fine till u got to a stop and rpm dropped to idle it would stall anyway tore the whole motor apart and found that the number 1 rod bearing was mia basically! which is crazy cuz i never had rod knock, ive had that with some other engines it was nuts1 anyways i was wondering id the non vtec crank is interchangeable?
