What would you do?

I'm looking for opinions on a 318 build I currently have in the shop. The application is for a 67 Fury (I know this is an A body forum, but the A engine is relevant), 3.23 gear, 727 trans with a stock converter, and is driven all over the country to historical landmarks, and to participate in parades. The car has a patriotic theme, and is invited to participate in many patriotic events. It can be seen at www.websfury.com.

Because of the extensive distances traveled, reliability, driveability, and efficiency is important. The car has a Performer manifold and 600 cfm carb, and exhaust manifolds. The engine was built previously by two other shops, but the owner was not satisfied with the results.

My questions are, since it is a near stock 318 build, would you spend the extra money to;

A. Torque plate hone the block?

B. Balance the rotating assembly?

Thoughts?
Without reading a single reply, I’d start with why he wasn’t happy? What was wrong with the engine? What did he expect from it.

For the sake of a happy customer and longevity for the engine, I’d spend the time and his money if he is willing to square deck and align hire the crank etc... so it would s perfect and just keep on going from there. Just go nuts making it super speedway endurance LeMans race worthy without racing parts.

Why?

It seems that it may be possible that this guy is just a nit picking ***** and whiner that will complain about what might not just be so.

When the super quality level of work is done and it runs smoother than a babies *** and hums along flawlessly, this guy is going to get you a lot of biz due to his happiness!
He just has to be told and have it explained to him like he is a wide eyed kid in need of a step by step with reason explaining of it all.

And have him understand that this is going to cost him.

If my old ‘79, 318 can log over 500,000 miles on a crap quality factory build with such whacked out perameters and off balance rotating assembly, that should go a million!
