That's good to hear, I may put a small kit on down the road...

Got some more street tuning done, just getting things fine-tuned at this point. Car runs and drives great.

Definitely an awesome build. Almost time for me to start the same process, so it's definitely motivating me seeing all your pics.

I've read over this thread a few times, still waiting on my LQ4 to FINALLY arrive after purchasing it a month ago, I was directly inspired by your swap to go ahead with the 6.0!

Can't wait to tear in to mine!

I bought an e-cutout with all the piping and clamps I needed from Summit last week and got it all installed today. Man this thing sounds awesome with the cutout open. Tuning is almost done, and the car drives great. Pulls hard. Stay tuned...

Not sure if anyone responded to your question about the timing chain set. Im not sure about the chain, but the cam sprocket isn't a LS2.

Amazing build I just found it and read all 10 pages, I'm currently debating what engine I wanted to swap in since my ls1 just crapped out. And after seeing this I definitely want to go with the LQ4 swap now. But I have a couple of questions, 1. do you know what the c/r is now with those heads 2. did you ever think about doing the l92 heads/l76 intake instead of the 2.5 and ls6? I'm trying to decide what combo I'd go with and any insight would help

Compression is 10.55:1. The L92 heads are the hot ticket right now, and I'm sure you could make some good power them, although I'm not sure what the combustion chamber CC is, so I don't know what kind of compression ratio you'd be dealing with on the LQ4. If its a larger chamber, you'd be better suited to look at a LQ9 shortblock that has the flat-top pistons.

A 59cc head on the LQ4 shortblock would get you closer to 11:1, but limits your cam choice unless you flycut. I was happy with the 62cc heads because I had good compression that allowed me to run a decent size cam without flycutting...

Hope this helps. Good luck with your build!

Nice build. I am thinking about a LQ4 or LQ9 swap into a 2nd gen. Can't decide if I want L92 or LS6 heads. I will go with a PatG cam either way. Subscribing for dyno/track numbers!
