I have and 88 c1500 that needs a new motor becuase the original 350 in it is tired. I was looking at two options. Either a 6.0 with a blower or and ls1 with a rear mount turbo. Let me know you opinions.

ls1 is usually more expensive and both motors are awesome. i say whichever great deal you run across first wins. im runnin a LS1 only because i got it dirt cheap. i would run a lq4 or lq9 (both 6.0's) anyday.

So ive decided to go with the 6.0. Should i go lq4 or lq9? Im bolting up a built th400 trans. Possible blower or turbo.




EDIT: not my, buddy on wrong account

blown application? go with a LQ4, with forced induction you don't need the higher compression LQ9, which would usually cost more anyway.... much easier to find a LQ4 also (normally)

Go with the LQ4 if you want to Boost it

I say go with the lq4 and boost the livin shit outa it!!!!!!

6.0l! Ftw :nod:

6.0l! Ftw :nod:

ls1 ftw :nod: (im biased)

Would you go with a LQ4(or LQ9) over an LS2 when you're thinking about giggle gas or huffer in the future? I just want to get in the low 12's with a 4800lbs truck.

ls1 ftw :nod: (im biased)

Lemme get a bigger money tree, and I'd beat your LS1. :devil:

bring it:punch:

i know this is old but id rather bring it back from the dead. i myself would like to run a 6.0 but the advantages of the alum block helpin me shed weight would be sweet also. im looking for around 550 wheel with nitrous. shouldnt this be easily had with a ls1 with soem rod bolts?

i say get whichever motor you can find for the cheapest. 550 is doable with a ls1 and nitrous. i put down 409 on motor. its doable with a 6.0 too.

I am running a LQ4 with a small cam, headers and a MP 122 supercharger through a 4L80E in my 47. Runs good with about 9 psi. with 4.10s I get about 17 mpg at 70 mph. Truck weighs 3200.45982

that truck sounds awesome!

Much agreed.

how can you tell the difference from a lq4 and lq9 by not taking the heads off?

Call a GM dealer with the number, they can tell you.

Lq9 is a vin code (n) lq4 is a vin code (u) THIS WILL BE THE 8TH DIGIT IN THE FULL VIN COUNTING FROM LEFT TO RIGHT.
