LS6 intake swap Q's.
 

Should I plug the back coolant line or run two front cross over pipes?

Either one will do I think but given the choice I would likely run two front pipes. :nod:

:werd:

I just shaved off the waffle grid on the bottom of the LS6 with a dremel. Worked great, and I didnt have to F with pipes at all, or buy any new parts. :D

I just did my LS6 intake/jantzer tb and since I'm ghetto and poor I took the stock lines to work and cut the the pipe going through the middle out, smashed the end on in a vice and brazed it shut. Did the same with the rear pipes except I just made them into plugs the same way.

I'm about to do this, but none of what yall are saying makes since. What am I going to need to do my intake swap?

If none of this makes since, don't do it :jest:

The LS1 intake has a path under it that allows the coolant line to go navigate to the back of the motor. The LS6 intake does not have this path. It is flat, so no lines can go under it. You need a coolant pipe for the front and plugs for the back.

Take a looky looky.. Click me

That's what I'm going to do with mine. :nod:

aren't there kits that you can buy that make the swap easy?

Yes, but for some reason the local dealers here say the rear plugs are on 1-2 week back order.

make your own?
