I built a 391' sbc back in the the late 80s i had to stroke notch the block by hand what a pain in the ass! this is the way to go, with a machine like that who needs a Dart block!!!
Fantastic Machine!! I wonder what an engine builder from the 70's would have said if he saw this machine doing this type of machining back in the 70's.
I was actually asking my instructor (at the school of automotive machinists) if people did all the boring/surfacing on cnc machines. I stumbled upon this LOL
Do you install and torque down plates before you hone the cylinders to size and finish ? Excellent video. It's nice accomplishing all these machining processes in one set up so everything is accurate to each other.
Proceedure sequences is not how I would do it for best final result. While I'm not opposed to it, there are better ways of doing 4bolt main conversions for the Chevrolet Engines. Coolant off isn't a good idea ethier.
dear precision race engines , do you know how big an oversized sleeve for a dart block could be done, maybe not quite an LS although iwas looking at making some hard rock 5150 chromium cooked zitanium steel alloy sleeves to go in my 400 DART small block, iwant to see how huge icould go if I sleeved the crap out of it with big sleeves how far icould go, with heat as non issue, could this be done? also trying to figure out how to machine an indestructible big cube small light weight engine but I cant cut the material at all, doesn't even scratch if I strike it with a sledgehammer. has anyone else been getting really tuff metal lately? like in the world? lol. the coatings iuse is a specially formulated and balanced epoxy with silicatanin molecular hard bonding its part of the alloy recipe now.
The cylinders are siamesed and 4.185" is recommended max bore.I have no idea about bigger sleeves. I would not suggest it but you could contact Dart to be sure.

Holy shit I've never enjoyed seeing a sbc so much, probably because the machine is what I was watching

Always use the most accurate tools . That’s is a fabulous fly cutter

Chevy Fan he would say. HUH and how accurate
I don't know how to program computer c nc lathe m g
Take me to your leader

I still find it funny people say "Blueprint Specs" . Especially in the CNC machining environment.
This is really cool! Thanks for posting.
You could save time by using CNC spot drills, instead of spotting with and end mill and center drilling..JS
:o) great job, what cost, because need a block for a 434 stroker.
i am that i am.
Awesome machine...Retired Larry
why did you drill the side cap bolts straight down? I would have splayed them on a 2bolt block.
Thats what the customer wanted. They didnt want to spend extra for splayed caps.
oh, ok cool, curious how much more could it be? iguess it all starts really hitting the pocket every little bit counts thanks for the reply

all done in half the time nowadays,where is it going to end?
How much do these blocks go for ?
why don't you put a deck plate on before boring out?
That's for the final hone.
I need this

thanks you
Too bad it can't line hone then be a 1 stop shop for block I guess
Bet that CC cost a pretty penny.
I am cylinder boarding work block cylinder boring
man you skipped through all the good stuff lol
