bring it

 

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.

 

that truck sounds awesome!

 

Much agreed.

 

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

 

VIN stamped on block

 

whats the difference in the VIN?

 

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