We start with a .035" Under Sized Bore Block. The block is then matched up with a side cover and line bored with a EZ-Bore machine, honed with a Sunnen Hone to .002" piston clarence.
The block is decked so the piston will be about .008"- .010" in the hole.
This comes with a standard piston that was used to size the piston clarence.
We also offer this block finished honed, finished honed and not decked.
We have sold a lot of these blocks to majar engine builders.
