Fixed my HVAC issue, We got COLD AIR! Since I had to actually work the Monday after the 4th and its kinda dead in the office, I thought I'd post a quick story.
Back in the Winter I decided that my Vengence Racing Ported Fast 90/90 was a bit over kill and I needed some cash for other things so I decided to take cash and a partial trade on a used LS6 intake.
Previously I posted about my broken fuel line lock from the rail to line and after 8 hr's of ******* with it, we cut it and I got a new factory fuel line, and also a correct, plastic fitting to unhook these locks.
Well since the swap I had a Lean code (Bank 1 and Bank 2) which depicted MAF issue OR that I am getting UN-metered air in the motor. The odd part was that it ran fine, only an occasional stumble in 6th rolling 2,500 rpms on the freeway and if I hit the gas.....
Also during the Spring I never use my Air Condidtioning or Heat, or even the defrost vents. But 1 month ago it was HOT after work and I had the car and no A/C was blowing and seems like it was a weak stream, and I could not switch which vents to use.
After Diagnosing that it was most likely due to the intake swap. I felt back there and felt on the "T" fitting that the HVAC line was not hooked up when I reinstalled the intake in a hurry (idiot).
I had the intake off this past friday in 30 minutes flat and thats with all the rats nest of a engine harness in the way. Using Blue Painters take to keep the rear bolts up and for the 3rd time no damage to the oil pressure sensor.
I found that the hard/flexiable line was crushed between the cyl head and intake which probably created a bad leak on one cyl and the small (1/8") "T" fitting wide open.
Being crushed I had to cut the line and find a replacement. Took a quick spin to Autozone and $0.89 later I had a line that fit snug, and I used 6 inches. Some white Lithium Grease on the hard line end and put it on the "T" fitting. I had her back together with in 25 minutes or quicker there after and had her blowing hard A/C immediately upon the start up and the car seemed to behave a lot better.
What was annoying was that the car compensated for the un metered air and only in rare situations did the car have a stumble.
A nice result was not only COLD A/C. That the car with the new slicks left a sick strip on a road that I frequent. I have to go back and check it out but I will be soon back to the track for some M/T ET Street Radial times and in the fall its time for Bias Ply's

She has a job that pays nearly as good as mine, and 5 minute drive and we have double benefits to pay for everything. Now we dig out of debt and go from there.
I managed to get most of my parts on deals and steals.
I have a UMI TQ Arm Relocation Kit to install soon, and a DS Safety Loop. At the same time I want to do a oil change and clutch fluid change and set the Rear sway bar. I will have to set the Shocks at the Track which should be 2's in the front and 7's in the rear and do some runs.
I will PM you when I am ready which I would like to say by August.

To be honest, I really did not feel a difference between going from the Fast back to the LS6. I am sure there is a power diff if dyno'ed but I think some of the Low End TQ came back and sacrificed some top end hp. The car still pulls pretty damn good for it self.
I can dump the clutch on the street and it does leave a sick strip and thats always fun.
I'll have to heat up the M/T Street Radials when I get to the track to see if they got any real bite left.
IMO if you have one of the original Fast's that persay did not have a MAF hold down provision or NON stainless hardware, I would get rid of it. I got like 800 + a LS6 for my Ported/Painted Used intake with Matching 90mm TB. In the end I ended up doing ok.
