440 CI update? - ZR-1 Net Registry Forums

No Body would make the liners They Said The Block Was to week, So we used a set of Blanks had them machined by a cnc shop They made blue prints of the sleves Then To save a step we sent them to darton to have them made again turned down. they would have to buy new tooling to make the water holes in the flanges, Not cost effective they told us.
Now we have a cnc program written.

Next the block Went To Another Cnc Shop To be Machined for the sleves with a .0015 Press fit Top & Bottom.
Then Back to the engine shop To be bored & honed to fit pistons, & check Crank line bore to see if anything moved, It didn't
Now I Will Assemble It And Be Ready For BG
