6.0L engine build LQ4

6.0L engine build LQ4

Postby GBROWN [OP] » May 07 2013, 1:50am

So the conversion I thought of doing is just starting to seem completely impractical not to big of a surprise however I still have a strong motor with my 6.0 LQ4 :). I have heard many different ways of building this motor looking for any input really! I am curious to know how strong the bottom end really is stock? I have been told if you change it you are going out of your way to make power with this motor true or false ? Also have thought of the pro charger good or bad idea? Looking from something with good horsepower even better torque but still applicable to street applications

I have a heavily built LQ9 in the race car/Jeep thing. The weak point is the rods and pistons. If you plan to do anything with them, I'd HIGHLY suggest forged pistons and H-beam rods (I can tell you what they look like when they fail). I'm running PRC Stage 2.5 heads and matching cam from Texas Speed. LS1 intake too. Figure 500 ponies with that setup.

The absolute BEST place to call is CBM in Cali. http://www.cbmmotorsports.com/

The sky is the limit with the LS series motors. You would save money buy just buying a built longblock and going from there. Instead of building up the stock bottom end and adding a "stroker kit"

Stroker kit was just a thought :) I know I have some pretty impractical thoughts which is why I haven't dove in head first yet. Am really itching to get something figured out though

Yeah, that was a pricey one. You should've seen the gouges on the cylinder walls. CBM rebuilt me a new motor in 3.5 hours with the long block they had in stock. We put the new motor in in about 6 hours the afternoon before I ran King of the Hammers.

You can definitely stroke it. 408 is the typical size. Give Chris at CBM a call. They're absolutely top notch people in every sense of the word. They build 500 LS motors a year.

I'd feel kinda bad to just call them to waste their time in telling me what I need to do because I wouldn't be able to do any business with them living in North Carolina :(

I'd really kinda like to use the block I already have. Are they pretty reasonable with prices?
