What? Where did you get all that from? He's a writer for Hot Rod, Motor Trend and a couple other rags. That's it. Might want to do a bit more research.
yeah I did stretch the truth a bit there in back in 2000 he worked for gm. In 03 he was in engineering for gm performance parts to help them get that all up and running good. You are talking present I'm talking past wich is more relevant to ls1 rite. Ed Korner was in charge of that other stuff. What I originally said was it helps prevent issues with 7 not completely solve the problem.
NOW the "8's" question is an EASY answer, as I make engine blocks.
The Core Box must have support, the "green" circles, both top and bottom
The Core Sand must "flow" easily when the block is heated.
My latest direction was taken from Jim @ Racing Research.
I will call a GM engineer(ret), now a teacher @ ASU for more information on the #7 issue.
He was the TOP GM engineer on LS testing/LS program at the GM Proving Grounds.
Lance, BTW Jim placed sixty "thermo's" on the LS engine/head with no clear answer.
8Lug knows all and there is nothing to question so we can just go ahead and /Thread
yeah. I apologize dude. It's an interesting one a solution would be good. If cutting a head gasket works I'm all for it personally don't have enough experience to attempt it myself.
how bad is it hurt? split liner or just a scratch?
i agree we should get back on track. i'm all for a little spirited bullshitting for the sake of bench racing but lets chill with the name calling. way too much of that snarkyness on LS1tech as of late, myself included.

wow now this is cool stuff. Will be following. Good on ya mate.
You can't possibly believe that GM did away with something supposedly so important just to gain like 2hp. The steam vent isn't the problem. #7 runs hot on ALL of GM's V8's, this is nothing new. The back of every engine always runs hot.
Gains were a lot more than 2 HP, but I see you know everything there is to know, so proceed.

I have. There were no pictures of the factory piece. Now there are. You're welcome.
oof looks like that piece stuck and rocked the piston pretty good. surprised it didnt bend the rod.
you might get away with a hone. looks can be deceiving when your looking at a glossy surface from the side. i'd probably run a dingleball though there real quick so I can get a good look at it. just a passor two to take the gloss off. then check the bore for deformation with a dial bore gauge.

It's pretty significant so I'll have to take it to the machine shop and see what they say.
