Don’t even pull the intake off. 10:1 cr and boost is not that bad on a LS1 aluminum head. NGK TR7s and a little race gas and this thing will take 20# of well intercooled boost before knock sets in. The top ring will expand and break the piston top before it would detonate like this for as long as the tune is right or conservative. If you have to break the motor open do this and leave it be.

I knew it needed a reseal atleast, and the more I got into it, the more I noticed problems. > [@Willyville crew, Lunch?](https://forums.speedlife.net/t/willyville-crew-lunch/43794/120): > > That’s what I was saying. I’d copy what Hot Rod did, turn it down a little bit to be safe, and run it. I joke about Mike about racing/beating him with the Camaro, but this thing has the potential to suck it’s doors clean off if done right. It was all done on an engine dyno, apparently it was put into a car and it only made a hand full of miles and came apart. There is so much more of a dynamic load in the car than on an engine stand apparently it stresses the engines totally different. Who knows how true it is, its a news article anyways. Someone could say its still running in their car today, none us would know any different. > [@88slowmarro"](#): > > that got dropped or suttin , deff not a mechanical deal . Thats what it looks like. But I know it wasnt us. The motor came apart on the bench, I had autobody paper down on the bench to mark my parts and where they came from in the block. They sat there for a few weeks, collecting dust, literally, Then they were in the parts washer sitting there for a few days soaking, after that Bowman and I started cleaning them and found the crack. Nobody in the shop even goes near that bench and they are set back against the back wall, no way they could even get bumped off the bench and hit the floor. Since the truck was RAPED when i bought it for the motor, I wouldn’t doubt someone had them out in the past and fucked them up. Who knows. > [@W2H(want to have): Scrap](https://forums.speedlife.net/t/w2h-want-to-have-scrap/46974/40): > > 2 psi? try on start up. btw you dont need forged pistons, people run over 20 psi on hypereutectic pistons all the time. doubt you need more boost than that to run 10s. Nobody needs anything, I want HPZ! To stick to the original plan, and chill people out, ill just get the stock replacements and put it together. --- _[View the full topic](https://forums.speedlife.net/t/project-10sec-4k-4thgen/261223)._
