i have a 2000 5.3 truck engine and I was planning on running a ls6 intake manifold, what all needs modified or replaced? will a ls1 water pump help clear the ls6 intake?

 

Budget ?

Desired performance level ?

What kind of vehicle ?

Manual or Automatic transmission ?

Intended uses of vehicle ?

Do you have to pass Emissions / Inspection ?

 

Why would you use an LS6 intake on a 5.3? With stock cam, you wont see any difference and be out $300.

 

street/strip, and 10,54:1 compression forged pistons ls6 stage 2.5 heads and 125 shot, no budget

 

I would use the truck intake if you can clear it with the hood, longer runners, more torque, less compromised by space. If space/room is an issue and that is the reason for the change then yes go for it but you will need a few things. Like car style water pump, hardware, fuel rail, map sensor, possibly the steam line crossover, etc.

 

thanks
