I was wondering if any of you has attempted to rebuild one of these CONTRARY MOTORS ? 
The Rod and Main Bolts are Torque to Yield Bolts !!! 
I was able to Locate The Rod Bolts through GM ONLY !!! But they showed 2 different Main Bolts, and The Only Ones they could get is about 1/4 Inch Longer than my Originals ?
So I wonder if they just did away with the other part # that's DISCONTINUED, and are just using the ONLY AVAILABLE part #, because it will work for either application ?
THESE ARE THE ONLY MAIN BOLTS I CAN FIND ANYWHERE !!! I tried a set from ARP, and they wasn't even close to being the right one's.
Any help is much appreciated !!! 
Thanks, 
Kevin
