Just to throw in a question from the experienced guys(not trying to hijack) but what all else is involved to make this swap right? Can u just bold on the heads and roll with it or is it more in depth? Sorry forthe newb sounding question, I am just unfamiliar with what the conversion entails. Thanks

Depends on the year, I believe. But, yeah, you can pretty much just bolt on the heads and go. My LQ4 is an '02 block, so, all I had to do was bolt everything up, get a few adapters/extensions (because of my LS3/L92 topend) and it was ready to roll.

L92's are definately some of the best bang for the buck heads. But, you would have to ditch your MS4 for a different cam spec'd for L92's. If you've already got a nice set of ported heads, you might as well just get a short block and reuse your parts you already have. L92's would probably be more beneficial though.

Interesting, and thank you for the response!

So if someone were to just throw their stuff from their LS1 on to a LQ4 block, how much hp/tq difference would it make? And what are the benefits, other than being at a higher base power curve??? Im assuming its an iron block if I remember correctly, so I imagine again that it would be better to spray on for sure

Just trying to understand a bit better guys. I've been getting back into the scene slowly but I've forgotten more than most know I was a Toyota tech for a few years so I really stopped caring about GM stuff cuz I dealt with yoda's all day lol

An LQ9 would probably be better than an LQ4, unless you plan on boost, because an LQ9 has a slight bump in compression due to flat top pistons instead of the LQ4's dished pistons. LQ4's are cheaper and easier to come by though. That's why me and a lot of others have LQ4's.

Basically all that displacement is going to do is move your powerband, if you're going with the same valvetrain. An LS1 might even make a few extra crank hp because it'd be a little higher compression than an LQ4. You just won't have to spin the 6.0 quite as high to make the power.

Did you have to flycut the LQ4 pistons? I know the center of these pistons are dished but the edges come pretty close to the valves. My L92's are milled .030".

I cant find any LQ9s that cheap on ebay, even from LKQ. Seems like the LQ4's are going for $1000+ with 70k - 180k miles.
