Project's moving forward a little bit. Since my last pictures of the engine I have coil packs, an f-body pan and an LS2 water pump installed.

I wanted to take a moment to detail the process of putting an electric truck throttle body an an ls1/ls6 intake, because it's not quite just a bolt it on & forget it sort of thing.
The main problem is the conflict between the throttle body gasket shape and atmospheric vent port location on LS1 vs. the L33 (and I'm sure other Gen III DBW engines)

both ls1 and truck throttle bodies have the vent port by the butterfly, but the LS1's port goes to a hose fitting located in the throttle body, while the L33 unit passes through the manifold through a sealed off area in the gasket, and the fitting is in the intake manifold itself.
So what's the big problem?
If you were to just bolt up this truck throttle body to the ls1 intake, you'd have a big vaccum leak as the 1/2 inch vent hole just sucks in air unrestricted, past the butterfly to the manifold.
My solution was just to do away with the vent altogether. I did so by just filling the cavities in the throttle body with JB weld.

The epoxy was a little low in areas, but not anywhere where it would interfere with the gasket's sealing.

One other minor issue to address was the routing of the anti-icing coolant line in the throttle body. I know a lot of people do away with the thing altogether, but if you really look at one the coolant path barely touches the throttle body at all, it's just enough to add a slightly warm spot where ice would want to accumulate in certain weather conditions, so I decided to keep it. The outlet port was straight where it directly interfered with the upper radiator hose connection, so I just stuck a small allen wrench in there and bent it close to 90 degrees.

I tend to think ahead, but not always about the most important things. I had already plugged the factory EGR hole in my ls1 intake with an expanding rubber freeze plug. With concern to any heat fluctuations or oil mist possibly making the thing work loose, I took it a step further and modified this fender washer I had laying around to form a little hold-down plate to be sure it never comes out, even if I decide to boost it. MF'er shouldn't go anywhere now!


That's Jparker7's old intake manifold. Throttle cable mounting points were already broken off, but that didn't bother me.
