How do yo like it? Thinking of doing this myself. Good option or no? I want to build it sicka**. Money is not an option, looking for any advise. TIA

 

Only downfall I see with going with LS1 over a 6.0 is cost. LS1s usually go for a lot more than you came get a 6.0 for.
My LS1 made a huge difference over the 5.3 but its got a lot of miles and it felling a little worn out, so its time for something new. I'm in the process right now of building up a LQ9.

 

i was talking with richard at wcch earlier this week about some future mods , and he mentioned something about someone he knew having some LS1 crate engines they were selling for, i think, $3800. maybe he will chime in here and let us know for sure.

 

Right, but whats your take on performance, mods and stuff. I guess im looking at comparison between the 6.0 and the ls1.

 

i'd like to know as well, is the ls1 a direct fit for me 4.8l? will my intake manifold, exhaust, belts and what not fit the block?

 

Everything external that bolts to your 4.8 will bolt directly up to the LS1. I only had one bolt on the Alternator bracket that I couldn't use but theres like three other bolts so I didn't worry about it.

 

In reality they are both almost the exact same size (5.7 - 6.0) that all the mods you do would be the same for either one. One is not going to really perform better with the same mods than the other per say.
I think the main difference is the structual stability of them, where as the iron bolt is going to be able to handle more HP than the Alum block in stock form. But you shouldn't have to be worring about that unless you start pushing alot of boost, high revving, or spraying.

 

cool deal, thanks zick for all the help.

 

money is your only option, unless the vendors are accepting sexual favors.

I dont think the extra grand or two for the aluminum LS1 is worth it over the LQ9. Its 70 lbs out of 4500 (me its 5500 anway)

the LQ4/9 have better heads, more displacement and such.
you wont notice 70bs in a heavy truck

 

Well actually i should say there will be no price tag holding me back. Thanks for being politically correct.
