Engine torn down to short block on stand. 4 bolt main 454

What should be be done for peace of mind without getting crazy?

thanks

deck and square the block, align hone the block, resize the rods, arp rod bolts, balance the rotating assm, forged pistons and bore job, screen the lifter valley to catch any valve train parts id also set the small end of the rod up for a floating wrist pin.

Yeah to what Ratman says. Also, if the block needs to be bored & honed, then have the shop use torque plates during the procedure.

Try to find a racing shop in your area, they will do a lot better job than most normal auto repair shops. They are familiar with the techniques and requirements used on high performance engines. Plus they are often cheaper, and more familiar with Chevy motors because that is primarily what they work with.

If you dont want to go crazy, maybe you could just pull the main and rod bearings, inspect for abnormal wear, if they are ok, slap some new bearings in and new rod bolts, oil pump

The first thing to be done before any of the machine work is to get the heads, block ,crank , rods magnafluxed(test for cracks) to make sure you start off with something sound.

That what I would do if you dont want to get crazy.
