Pretty cool vid.

Lonny Doyle · 05-05-2012, 04:36 PM

This video is actually explaining how the ZL1 engine block is honed using deck plates to simulate cylinder heads being torqued on the block.

When you torque the cylinder heads and main caps onto the engine block it causes the cylinders to distort, so if you were to hone the block without deck plates and the main caps installed the cylinders would measure round and straight until you assembled the engine.

Once you installed the heads and main caps the cylinders would no longer be round and straight. So to prevent this from happening they simulate the engine as if it were assembled while they hone it by using deck plates.

Another thing we do while honing is to pump hot honing oil through the cooling jackets to simulate running conditions while honing. We bring the whole block up to around 180 degrees during honing.

Cool video and good info.

....outstanding, these motors should be close to most of the blueprint specs because of the dilligence Chevy has ensured thoughout the manufacturing process, way to go Chevy.....! Chevy engineering and manufacturing is cutting edge....

Very interesting. Thanks

Talk about perfection...

This is awesome!

SC2150 · 05-08-2012, 01:00 PM

Lonnie is correct. We hone no motors w/out a deck plate...only way to ensure the bore is square.

hot ss · 05-08-2012, 01:08 PM

this is news?
didnt know it was done any other way,
unless the build is in a garage.

I stroked and bored mine using a dremmel tool and a thousand attachments.

This makes me wanna go work on motors again...good stuff.

something tells me that you and chris would be the only two people that would do this..

Sounds like this honing process video is not just ZL1 related. Maybe not even only LS related?

From what I remember, most production blocks and assembly line rebuilders do not bore and hone with deckplates. When I had my engines rebuilt, you had to check this off and pay extra for it.

Thank you for posting this.

In the mid 70's I had a 383 LT-1 built using "stress plates" as they were called then, on the cylinder honing. That engine had almost no leakdown (as I recall around 2% or less). It does make a difference.

slicktempo · 05-09-2012, 01:03 PM

Very cool video! I was imaging the guy in the back just going..."Mmm ...ohhhhh yeahhh.." lol

Mike @ CMS · 05-09-2012, 01:21 PM

I do not know of a single engine built these days that is not honed in this manner. Deck plating is common practice in all factory and aftermarket engine build and has been for years.

vanlieremead · 05-09-2012, 09:57 PM

Is this done to all production engines, by hand? Wow! Is this only for the new ZL1 or did my 2011 L99 go through the same process?
