Over the past year or so we have been working to develop the worlds largest LS engine and have begun final machine work and moving towards assembly now. I am going to start a build thread here this week, but it might take a few days to sort through and begin posting photos.
Please keep in mind somethings we will not go into exact details but most things you guys should get to see pretty close up on how something like this is done. The plan is to engine dyno, do some cam testing, and then get them into vehicles for testing. The first two are being done side by side with one being a more dedicated drag race setup while the other is going to be a more radical "street" setup if you will. A more endurance/road race setup is on paper and might be possibly coming in 2019.
Well, if y'all want to put one into my car for a street test, feel free
In all seriousness: 527 is bloody massive. A full hundred CI over the LS7! Is this based off of a standard tall-deck aftermarket design? 454 with the skirting to support a huge stroke? Or is it an even taller deck?

This is based on a 9.750" tall deck RHS aluminum block, pictured above. We have done one other a few years ago, slightly smaller, at 523 CID but it was a hyd roller, pump gas, OE oil system....this will be a much more advanced build that that.
Assembly should officially start next week and we will work on getting pictures prepped and ready for posting along with a full detail of what all is going on.
The blog will feature this as things go together, not really how it was planned, to do that you would have to read the article in reverse.....starting with the intake.
So before I take off for the weekend I will leave you with one more sneak peek into the build showing off the 5 stage ARE dry sump that will be used on both 527's.
That is where we got our inspiration from to do and I believe we are 1/2 a cube larger (at this size its hard to go leaps and bounds bigger). Of course we are shooting for a bit lower cost than an all out race build with the canted valve heads like they are using too
We have been assembling both engines and they will be on display at PRI this year at the ARE dry sump both and CID cylinder head booth. If we don't get time for installment #1 on the write up before PRI, the build will start when we get back.
I feel special that I actually seen these engines in person and laid my hands on them as well. - Just way too cool! Love the Plexiglas panels to view the engine components. The ports in those heads are monstrous

It would a great show. Did you get to see both of them or just one?
