WKMCD 01-15-2010 06:55 PM

Maybe if we all PM'd Shawn at the same time he'd post some more great pics. :D :rofl:

Stevo92z28 01-15-2010 07:19 PM

nice progress kevin! Good reading here. SDxx? Scoogin Dickey?

You thinking of another caravan to pick your car up? I would be up for that if it's decent out. I'd like to check out that facility also.

Here are some pics of the sleeve machining and installation process.


http://i256.photobucket.com/albums/h...1-14-10025.jpg

first thing is the block setup in the cnc-here the probe is finding the crankshaft center line


http://i256.photobucket.com/albums/h...1-14-10026.jpg

now we find the camshaft centerline-this way we ensure the bores and decks are exactly 45 deg from the camshaft to crankshaft centerline


http://i256.photobucket.com/albums/h...1-14-10028.jpg

now we probe the bore locations to determine the location of the bores


http://i256.photobucket.com/albums/h...1-14-10030.jpg

now we probe the decks in 6 locations on each bank-this tells us the height and straightness of the decks


http://i256.photobucket.com/albums/h...1-14-10034.jpg

here is a report of the locations of the bores and the deck heights-the x locations in parenthesis are the blueprint locations the one beside them are actual.All y locations should be zero


http://i256.photobucket.com/albums/h...1-14-10035.jpg

here we are rough boring-this will get us to within .020 of the actual size


http://i256.photobucket.com/albums/h...1-14-10037.jpg

block after rough boring


http://i256.photobucket.com/albums/h...1-14-10039.jpg

couple shavings underneath


http://i256.photobucket.com/albums/h...1-14-10040.jpg

finish boring-we need to be within .0002 when finish boring-that's 2 ten thousanth's of an inch.Accuracy is really the key here-if not bored perfectly-you can crack the block when installing the sleeve or you can have a loose sleeve.There are not too many machines out there that can hold this accuracy-we are very fortunate to have one.

bores ready for sleeves

sleeves installed

ready for final machining

Shawn @ Va Speed 01-15-2010 09:11 PM

here is the block decked to the proper height-give or take .0001:D

hopefully next week i can get the block honed and rotating asy balanced-i got a lot of other blocks to hone as well

SDxx=Correct!

I've got a few guys want to make the trip. I'll count you in Steve. Follow the thread and you'll know when we're going down.

That is some beautiful engine porn there! Kevin, looks like the guys are doing some 1st class work on your project. Looking forward to our road trip to VA Speed when ready.

good job VA Speed...you and I know youre in good hands with them!

WKMCD 01-16-2010 06:55 AM

Round and flat is good! All of the machining within .0001 is :cool:

phils C5 vette 01-16-2010 07:38 AM

So Im hanging out with one of my kids this morning watching saturday morning cartoons, and I ask him " do you remember Kevin with the white corvette from Virginia". She says "yes". I say "look at these pictures. He's having a new 427 motor built" he looks at the pictures and says" is that good". I say " it will be good for a while tell kevin says it need more" :rofl:

Kids lol

LOL I gues the heads will be boxed up and shipped to Richard at WCCH (proheads.com)this week for his treatments. This is moving quickly but I think it will slow down a little now.

It's all good. :thumbs:

I wonder how it would run with a little boost...:crazy::willy:

McLeod 01-16-2010 07:49 AM

Oh boy.:willy:

Great pictures and details. Didn't know VA Speed had all of that fancy equipment.
