Went to the Junkyard yesterday and pulled what I hope is everything I need to do this conversion. The donor vehicle was 1989 Sierra GMC pickup. The ECM was an 1227747. The BCC is still to be determined. I did not see any where I thought they should be. However on the ECM with all the information it had ASKF. I believe that is the BCC ID. I'll have to check when I get home to confirm the order of the letters. When I did a BIN search those letters did not come up. Anyone know anything about this chip? I will be going through this step by using the information found on this site. The help here has been tremendous especially david w and Eaglemark. I will keep you posted as to my progress from time to time and seek advice. I am putting it on a 304 AMC bored to .30 over. I will check with the fellow that redid it to find the cam he used.
