Great solution to your problem. The whining Walbro pump makes me wonder if it was a clone pump. I never heard of a Walbro pump whining before this. Not that I am any fueling guru, LOL Now it sounds as good as it looks.

I got mine from Tanks Inc so I would hope it was a genuine pump. It was not whining like this when I installed it. The whine got worse and worse over time. I don't know if the pump had a defect or if there's something about the installation that cause it to fail over time. Perhaps Project GatTagO and I just had bad luck.

Andrew,
good to know. Thanks for clearing that up for me.

Weather in my are has cooled some so I decided it was time to get the heater working again on this car. To expedite getting the swap running a few years ago, I simply bypassed the heater outlets on the waterpump using Dayco 87629 as shown:
I started by draining the coolant and was happy to see it was clean and clear.
Then I had to drop the inner fender to get to the lower hose fitting on the heater core. This area is very tight on a factory AC car. I've done this hose swap before without dropping the inner fender and this made it WAY easier.
My factory AC car uses a vacuum-controlled shutoff to prevent any heat from the heater core from affecting maximum AC function. The original valve was a simple shutoff, but the LS style water pump relies on circulation for accurate thermostat function. So I used a bypass style heater valve, Four Seasons 74781 / Everco 5930. This valve normally allows coolant flow to the heater core, but under vacuum it returns the coolant flow back to the waterpump without passing it through the heater core.
Here is how the hoses route
With the system plumbed, I filled with 50/50 Prestone/Sparkletts distilled water
And here's the engine bay nicely cluttered with hoses and lines.
With that done the heater works GREAT. It can easily bake me out of the car so driving in cold weather is not a problem. Here are a couple photos I snapped from a Sunday drive this weekend. We were between rain storms, so it was a good time to get out and find puddles for reflection shots.
I am really happy now that the fuel pump has quieted down, but it's made other squeaks and rattles much more noticeable. Related to the LS swap, I'm starting to get some belt noise. There is also a weird squeak from the package tray area inside the car that's driving me crazy. Just goes to show there is always room for improvement. This car is definitely a driver though and it brings a smile to my face every day, especially when I find a safe place to have a little fun.

great build!
I might have missed it, but how did you end up fixing the oil pan/tie rid hitting issue? i have the exact same problem with my camaro (full lock) and trying to find a way to limit steering.

The tie rod ends (TREs) were hitting the pan when I had the engine set in a lifted, 1/4" forward position: see post #162. Later I moved the engine it a non-lifted, 0" setback (post 193) and still had interference at the TREs and the headers. Finally, I settled on Dougs SK100 adapters which have a 1/2" setback position. That did the trick both for header clearance and TRE clearance. As an added bonus I didn't have to modify my driveshaft because the transmission was pretty close to where it was originally with the 1/2" setback.

A couple weeks ago great old friend of mine visited. We spent two days driving all over in the Nova, including a jaunt down the Pacific Coast Highway and up Deer Creek Road south of Point Magu. The Nova did great and we even enjoyed the AC when the weather warmed up.
I also had a chance to meet up with some car folks I met through Instagram: @slayer_camaro with his 5.3-swap turbo Camaro and @benkahan with his '65 Mustang. Ben is a young aspiring filmmaker who has been producing under the name "4 Speed Films".
