Message I've been here for a long time and have never seen an actual pics of machine and balancing work on the block, and I thought that it might be helpfull to others.

The balancing was done since the rods were lightened/matched to the lowest one as well as the forged pistons were considerably lighter than stock. I was surprised how big the deviation in the weight of the rods was. The crank journals were also micropolished, as part of the balancing job. All in all, the balancing was about $250 from a high performance machine shop that does race-boat engines. As expected the Auto-Specialty UD pulley had close to perfect balance, and the clutch pressure plate needed the most correction. I deburred/polished some of the crank surfaces myself.

The Boring being done, .5mm over using a Sunnen machine.
The owner there also said that torque plates were a hit/miss thing and mostly beneficial in unsymentrical head bolt pattern/ sleeve applications where block flex was more pronounced. They used a torque plate on a V8 apps, and when they torqued it each time the bore measurements varied. I had the option to use one, but chose not to as the investment seemed to outway the benefits atleast in my mind.



Any comments are welcome.
Regards,

George
