Any updates on this? Can you use an LFX Short Block in an LLT car?

The blocks are almost identical, if you're trying to put the LFX block on LLT heads you will need new exhaust to match though. Doesn't seem worth it, LLT block you can put headers which is one reason people wanted to to put the LLT block on the LFX heads. Opposite of what you're asking for

No, people are wondering and wanting to know about using LLT heads on the LFX shortblock. Exhaust connects to the heads not the block.

Chris Bacak is building an LFX with LLT heads right now. Not sure if he's on here, he's on the Facebook pages for v6 camaro performance.

LFX block that I will be boring, maybe stroking. Ported and polished LLT heads that are getting larger valves

I'm also in the making of putting LLT heads on an LFX block. I'm told from the LFX/LLT guru Tracy that this is possible and that you will end result have more gains being the LLT heads can be ported. You can put larger valves on the LLT heads but it will be the same size as the LFX valves being the LFX valves are larger to begin with. Currently myself personally i'm having a set of LLT heads being ported and get larger valves with 5 angle valve grind and Mace cams. Once I install them on the motor and check my clearances i'll let you guy's know if everything checks out. I went this route due to the LFX you literally can't do anything to them and no machine shop will dare tackle the integrated exhaust manifold style.

Oof. Don't refer to Tracy as a "guru"
Better term would be a "charlatan"
