What I want to do is take out my 5.3 and put in a 6.0. But i'm not gonna supercharge it or torbo it. I know I should but due to funds thats will be a long ways away or never. Will it be a big gain? is it worth the money? I know that a supercharger wil be easier to put on my 5.3 but I want a 6.0 goddammit! and is there a place I can buy one for a good price? can i just go to the dealership and place an order?
Should i track one down at a junkyard with the 4L80E (doed it have the 80 or 85?) already bolted up and make a simple swap? Can it be done in my 2wd sbrc 04 truck?
I know a lot of questions and this has been kind of brought up before but its a good subject. Thanks

 

If you want to find a LQ9 with a 4L80-E look here: www.car-part.com

you may find that some billet servos and a **** kit with the Supercharger may be a better option in the long run. Going from a 5.3 to a 6.0 is not going to net you major HP.

 

LQ9 only comes with a 4L65E

 

Opps, if you want a LQ-4 with a 4L80-E look here: www.car-part.com

 

Would a LQ9 or a LQ4 be better considering cost and power?

 

For a mild NA setup the LQ9 might be better,but if you go with a FI setup the LQ4 is better.There's so little difference in performance that I would have trouble justifing the difference in cost the LQ9 will cost you a lot more money.You could spend the difference for mods that would make the LQ4 a lot faster than a stock LQ9.

 

What do you plan on doing to the 6.0? What type of numbers are you hoping for? I know the 6.0 can be built into a pretty good motor while still being NA, but not sure if the difference in money after mods are added to a 6.0 will stack up to your 5.3 with a supercharger. Good luck with your decision.

I'm not looking for a really fast 1/4 et time just a fast truck that I can drive daily and last a long time(and beat some other truck on the road) . I don't want to blow my trans or greatly reduce its life i want a good engine and trans combo. Slight mod to the engine to give a little power but nothing crazy. or would I be better off putting a supercharger or turbo on my 5.3 with the 4L60E 3.73:1 and the G80 locker?
Will the 4L60E hold up just as long as the 5.3L?

 

For just a little bit of money compared to a complete 6.0 swap or supercharger, have you ever thought of gears and a chip? Low gears help a lot and with a good tune, I would think your truck would be fast and very powerful. A 2wd reg cab should be quick as is, but with just a little help it could be very impressive.
Good luck,
Jordan

 

i'd recomend going with an LQ9 and 4L65E and sell your 5.3 and 4L60E to make up some of the difference.
