Internal engine questions
Sleeving From $725-775 (we beat any advertised price on sleeving)
Block Assembly $400-$500
Blueprinting $250
Crank Balancing $100
Crank Polishing $40
Crank Knifing & Balance (lightening) $375
Boring/Hone/Hot Tank/Deck $175-$200
All new bearings & thrusts in your block: $217
Seals (price varies)
This is a price list from importbuilders.com.
What does hone/hot tank/deck refer to? Also, what does knife edging the crank do and what are thrusts?
Thanks for any help.
I'm trying to learn as much as possible before I get my swap so expect a lot more q's.

Honing is a process thay smooths out imperfections in the cylinder walls and leaves a cross-hatch pattern that aids in the seating of piston rings.
Hot tanking is exactly what it sounds like. Whatever is being worked(block, head) on is submerged in a hot tank(go figure
) of solution which cleans it.
Decking is milling the deck of the block so that it is uniformly flat. The amount of material removed can be kept to a minimum, or it can be specified by the customer.
The lobes(I don't know what the technical name for them is, so I'll call them lobes) on a typical stock crank are kinda square/round looking. Knife-edging a crank is when these lobes are machined so that they taper to a point. This, in theory, results in less rotating mass and reduces resistance against any oil that the crank may be rotating thru.
Thrusts are thrust washers, I assume. They shim the crank laterally in the block.

They're called crank counter-balances. Everything else is correct.

If/When they are boring the cylinders it's a good idea to use a torque plate. Basically it's a metal plate with holes knocked out for the cylinders that gets mounted and torqued to the block (via the head studs) in the same fashion that the cylinder head would. Once mounted and torqued then the boring of the cylinders begins.
This takes into account any flex that the block/cylinders might have and will create more perfectly round bores.
