no its not.. the truck's water pump outlet is higher than the car's... thats why we have to convert to car accessories to run a car type intake manifold...

And another quick question... The spread of the heads in a 4.8 is the same as a 5.7 ??? Meaning the manifolds interchage easely ?

yeah, but the truck intake flows the same as an LS1 intake until you get way up in the RPM's... what are you working on and what are your goals? I might be able to help a little better knowing that. FYI though, the 4.8/5.3 block is the same exact external dimensions as an LS1 or a 6.0L block... most everyhting will interchange between the 3 blocks... they're all GEN III motors.

Ok... well I'm shopping for a truck and I like knowing what I could do to it later down the road.

It's high miles 2000 4.8

From the looks of it, an ls1 motor would be a direct replacement... ? I could reuse ALL of my 4.8l stuff ??

a LS1 shortblock will sit right under all the truck stuff and you'll never know it... unless you look down and see an aluminum block hiding out. go to performancetrucks.net (LS1Tech's sister site) and search for a guy by the name of TXsilverado or beastmode, they're two of LS1 swapped trucks there, there's plenty more, but they have pulled it off nicely.
