Building the worlds largest LS - HPR527
 

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.

Stay tuned!!!

Sub'd! :cool::lurk:

100ci over stock?? Wow.

Sick. Just plain sick.

That is all.

Are you going to use a deck spacer or what? 4.165 and 4.600 doesn't get to 527. Either that or you're tacking a couple more cylinders on ;)

What is the bore and stroke going to be?

Here ya go :thumbs: https://www.enginebuildermag.com/201...id-ls1-engine/

“On these engines we can only use Cometic because, even with a taller deck, to get our piston right we run the piston way out of the hole and we’ll use real tall head gaskets they make that are like .150˝ tall. They have a built-in aluminum spacer in them."

All in good time.

There is no deck spacer being used, bore is less than 4.200"

subd! 😃

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.

Whaaaaaa!!!111!!1?

While I gather pics and do the write up's I'll give you guys some teaser video's along the way..

That's poking out quite a bit! Boosted application?

This looks like its going to be an awesome thread.:cool:

NA only on these.

Is the piston shape for quench?

Longer rods to slow the piston due to high stroke leaves very thin crowns
