Just installed the 355 this morning and began putting the front of the motor together and when I was putting the power steering pump on the motor I found that it hit the 8" balancer, no problem, I had a 6.75" ready to install. I don`t know where this "THING" came from but it did not fit a SBC. I had a buddy come over with a caliper and found it to be .003 smaller than a typical balancer. I then decided to use the balancer from the 283 that came out of it and cleaned and painted and began installing when I got maybe half way and found there was a heli-coil (hope I spelled it right).
Removed the Balancer and tried to go with a larger size bolt and it started out good but again got half way and it started to feel like I was stipping threads. All I need is a stinking balancer on this motor and I`ll be alright, What do I need to do???
