What was the year models and applications for the engines with the sand cast blocks?
I definitely want to go ahead and pick one up to start on for when my current engine bites the dust.
Also it would be helpful if someone with the knowledge and experience of these engines could advise how much they can safely be bored and still remain a dependable daily driver with the SC installed.
Inquiring minds would like to know! LOL
This is a copy and paste for ddmworks site....so all our blocks are foam casted unless upgraded
We are happy to now offer 3rd gen blocks as a build option. What are 3rd gen blocks? The original LE5/LE9 engine found in the Slingshot has its block cast by a process called "lost foam". During this process a styrofoam engine core is placed in sand and molten aluminum is poured into the mold were the aluminum replaces the styrofoam. If you look closely at the side of the stock engine, you will see the surface looks like styofoam because of this process. This lost foam process allowed GM to cast a complicated engine relatively easily, however it was found to cause a weak point that can allow small cracks to form in the block. This led GM to improve the block during the next revision with a sand cast version of the block. The new 3rd gen sand cast block gives a more uniform finish in the block and is less prone to cracking found in the lost foam castings. GM didn't just stop there though with that improvements to this block, they also added more material to the inside of the block to strengthen the block internally. The most important upgrade however came to the cylinder bores themselves. The stock LE5/LE9 has floating cylinder bores, which mean that the top of the cylinder bores are not secured to the block, the new 3rd gen blocks added material at the top of the cylinder bores to bridge and stabilize the tops of the bores. This bridge also increased the amount of aluminum around the top of the bores to help strengthen the cylinders even more against higher cylinder pressures found with high horsepower builds.

??? If you notice, somebody with a sharpie wrote BAD. Not encouraging.
I'm assuming that's marked to be decked since you see all the yellow x's as well

I don't want to derail the thread but since I know there are several people following this thread that are already boosted, could I get someone to email me the "detailed instructions" for the DDMWorks supercharger install.
I am almost finished with the insulating and ready to set the drive train back in and begin the SC install and for the life of me I can't find the instructions. I wanted to read over them a couple times before I started.
Thanks in advance!

Looking at the alpha brackets looks like you can mount almost any universal spoiler vs doing the bundles most of these dealers are selling am wrong?
