Im no pro but whenever I use hardblok I use it on both banks. I pour it in,tap the block slightly to ensure a consistant fill then bolt a set of torque plates or heads on as it dries. I would hardblok the otherside also. Sounds like a half azz job to me.Literally. Fill the other side to the same level as the filled side. Normally hardblock is used before any machining is done.Personally I would be pissed and would be on a 3 year retirement for a severe boot stomping.

Check to make sure the block has not distorted.

I can't imagine any one filling only one side. That would be like running two 4 cylinder engines. Although slight, the different heat would make a difference in the tune and probably the harmonics as well.

These were my thoughts also and when this is the first engine that i EVER had built for me, I have always built my own engines as that is my trade ,but you always think sometimes it could be built better and secondly this was the most i have invested ever in a sbc .Should i pull it back done and finish job or run it as he says its ok. :roll: :roll: :roll:

They probably poured it in one side and then realized it was a bad idea, so they stoped
