Ok here is the start of the engine block.
Stock crank on the left, billet stroker crank on the right
After sleeve install, the block is then step decked. This helps concentrate the clamping force around the cylinders.
Boring the Darton Sleeves to 100mm.
Notching the bottom of the Darton Sleeve for oil squirter clearance
Oil squirter notched.
Machining 2 of the 4 main stud for 1/2" studs
More to come.....

The journals have already been polished and cleaned up. Knife edging the crank is usually done to remove or "lighten" the counterweights on the crank. In most turbo applications, you tend to want to leave the weight on there, but most N/A applications is when knife edging is performed.

Why would you want to leave the weight on there in a turbo application? More load on the motor to help spool the turbos up or to keep the strength in the crank?
