how much power can a 2011 buick lhu block handle ??? Thinking about switching to that motor i lost a cylinder wall lol.

 

how did that happen?

 

I'm not sure if you can put the LHU motor in?

 

zzp has LDK shortblocks on their websight that handle 500 hp stock, is that what you are referring to?

 

Thats the one

 

Yeah I have the LDK, but I don't think the LHU will lol.

 

i've already seen 2012' GS LHU stock block dyno at 560hp w/e85/35psi - with cylinder #1 & #3 cracked from top to bottom.

the LHU & LDK blocks alone can handle up to 460-480'ish with a reliable tune..

Past 550+ the block needs to be girdled, these blocks in stock form weren't meant for high boost - over 30+psi, using a girdle system will prevent this from happening..

 

Was that from detonation though? I was told by a big source that an LDK Generation 3 with wiesecos and rods could handle 700whp.

Specifically why I bought a 3rd generation LAF to run as a 2.1

 

yep, from detonation..
