I just don't understand why there so much? For instance a stroker kit is what $1200-$1400 Rings and bearings like $120... Boring is what $200... Where is the rest of the cost?
So if someone has a offset ground crank or even a stock crank it be even cheaper....
Not trying to be rude just curious
A properly built shortblock is not just a collection of parts. Labor and knowledge are not free
, and offset ground cranks are not cheaper than cranks made in China.
But, lets add some basics to your list....
-cost of a core block
-teardown of core engine
-hot tank/clean block
-magnaflux the block to check for cracks
-line hone (if needed)
-balance rotating assembly
-fit pins to rods/pistons
-check/correct rods for straightness and/or recondition them
-juggle several sets of bearings to set clearances
-file fit rings
-assemble engine and measure deck
-tear down engine
-install cam bearings and freeze plugs (plus the cost of cam bearings and freeze plugs)
-re-assemble engine re-checking clearances
-measure/set rod bolt stretch
-rear main seal
-mask and paint
