you have to notch the sleeve,it does protrude below the bottom of the cylinder,but nothing major.yes you can do ls3 or ls7 blocks-just normally is cost prohibitive unless you have one with a bad sleeve already

How many miles could you expect in a street car with a Darton sleeved 427?

Shawn. This is a really nice presentation of the precision machining required for proper sleeving and block prep. The final result is a solid foundation for a performance build. Thanks for taking the time to show the step by step process.
Kevin is doing a great job keeping pace with the changing demand for larger displacement engines and spotlighting the technological progress of building a potent street machine. His decision to stick with the L92 heads will help demonstrate the true power potential of this mass produced part. It's truly an impressive production design.
Nice work Kevin

I think that goes without saying Kevin.
So when you originally had the 403 built, was this already discussed (resleeving the block and making it a 427 down the road) and you were just waiting for the right time to do it?

When I bought the short it was because my 346 had cracked a liner. I had no intention of going bigger. The 403 needed to be freshened and when Shawn and I got to talking...for the cost of doing liners I could make it a 427 and be much stronger in the long run. Nothing sexier than a 427. It's just a classic number.

Good luck Kevin, between this thread and a couple other ones here on tech there is certainly a lot of anticipation on the upcoming results.

Oh ok. You are right about a 427 in a c5 being sexy !!! I might be able to top that, how about Halle Berry in some 5" stillettos, white thigh highes and a thong ? Maybe thats just my idea of sexy, who knows. LOL Maybe Jessica Biel in the same outfit (black) is more your speed, I'd be fine with either one.

The heads are on their way to Richard at WCCH. New CNC program and 2.20 intake valve. I've been running stock L92 vales all this time with no problems but we're going to upgrade the exhaust to stainless also while we're at it.
That is all.

Shawn put up some more pics. All captions are from Shawn at VA Speed.
In the hone with torque plate installed
Here's a picture of the diamond hone stones.These last much longer than the old vitrified stones-they also make a cleaner cut and less tearout.The other benefit is less honing pressure which keeps rounder bores for much better ring seal
Here we are honing.I try to keep the bores within .0001'' of roundness and taper
Here's a screenshot of the readout on the hone.The image to the right is an exaggerated image of the bore,top to bottom
After cleaning the block,here we are in the build room,ready to start measuring and assembly
