440 CI update? - Page 2 - ZR-1 Net Registry Forums

Bob G · 12-17-2008

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

Once you "pathfinders" have blazed a trail thru the CNC programming and parts sources...I'm very curious to hear what the prevailing $$ tag is going to be for tossin' a set of sleeves an buckets in to our LT5s is going to be? I thought I read somewhere that a conversion (depending on needing a crank, etc,) might be well under $10k?? THAT would put a lot of us over to the "dark side" for sure!!

current "440" 4.100/.125 bore blocks are from $6,500 to $13,500

This is the range I have heard from the 3 big bore guys, This is only the block and sleeve work. You must have the bucks and will to go this route. As the cost for the rest of your stroker is added into from the price above.

sweet! we just need to get nelson or somebody to step up and make a cnc billet block to allow these big bore deals

13,500 to mod the block is a bit much.

who was the "big guy" who would do it for 6,500

pretty big price range!!
