Default FAST Intake with 98-00 Coolant lines?

Before I bolt done my FAST intake I just want to make sure that it will work with the 98-00 coolant lines that run underneath it, ive never seen anybody say you have to change this out with the FAST only the LS6.

Anybody know?

You have to use the LS6 coolant lines. Be sure to install the special button head bolts on the valley cover also. Failure to do either one of the two will break the intake.

If you take a hammer and slightly oval the tubing, you can keep the 98-00 coolant tubes with no problem with an LS6 or FAST intake.

It takes all of 5 minutes to swap out the coolant lines. You are spending over 1000 on a great intake why skimp on such cheap parts.

I've done it twice with no issues.....and it's worked perfect, why block off two holes that move coolant any from the heads when you don't need to??

You've done it twice on a FAST? You can't even run the stock valley cover bolts. The line would have to be so flat that it wouldn't flow any coolant anyway and the chances are good that you might collapse the pipe all together.

GM thought it was OK to block off those back two ports. And they've done it on everything since 2001. I'm sure they would have at least connected the back ones to each other if they saw fit.

Exactly!!!

This is also the reason I hate seeing post where people bitch about breaking stuff and trying to place blame on parts and companies.

People purposefully do not follow specific instructions, break parts, and whine about it publicly. When it their own fault.

Even if people break stuff "thinking" they did everything right, they rarely get any of the blame.

I'm mistaken, I've done it three times, two times on LS6 intake installs on two differant cars and on a FAST.....my FAST. And the lines are no where near flat enough to not flow coolant. This is just what I've done, I know GM okays the fact that the back two are blocked off after 2001, thats fine, and if I had a 2001 or newer I wouldn't care about the back two, but for those of us that have a 98-00.......like me....who doesn't want to throw more $$$ at an easy solution, this is what I did instead.

If it works, it works. I've only FAST installs on car with factory LS6 intakes. If you can pull it off, do it. If you **** it up, then by the other stuff.
