Has anyone ever used block filler in their block? I know Honda guys do it in the B & D series engines. They'll fill the block with kosher salt, leaving a .5-1" space from the deck surface. Then they'll pour DEVCON Liquid Aluminum Epoxy/ Block Filler to the deck surface. Once it baked and cured, take the freeze plugs out and flush the block. I heard of B-series blocks making 700+hp with this done on stock sleeves.

I was looking to try this on a LSJ or a LAP block. I figured you could pour this on the bottom of the coolant jackets on the Gen 2 block and they might eliminate the cracking. The LSJ block would be cheaper to do and looks more likely to work. I have Gen 3 rods and piston to put in it afterwards. I was looking to making 550-600hp on stock internals. I'm trying to do a budget build without buying a aftermarket block or Gen 3 block.

 

Ya if u never wanna drive it more than a half mile at a time

 

Or just get a Mr B sleeved block...

 

They're driving them with no over heating problems. Some say it's stronger than a pressed in .5" block guard because you can make them thicker.

 

there is no way to successfully do that to an ecotec block there are no core plugs to remove to get the salt out and there is no way to get the salt out

 

^^^^ this and honestly block fill should only be used when using alcohol or nitro imho

 

Leave the salt in. Sodium filled block.
