LQ4 into a 3rd Gen/1972 Nova by frojoe

The radiator P/N is 802-31191

And the upper outlet is a -20 o-ring port thread, I guess to make the rad more universal/flexible for more applications. I got a 1.5" inlet, P/N 78-00104

I'll let you know how much of the rad support needs to be cut away to allow airflow for the 28" wide core, possibly after this weekend if I'm productive.

Made some aluminum sleeves to better locate the 1/2" holes on the hotside flanges to the M10 bolts required by the CTS-V exhaust manifold flanges..

Also cut off the driver side wastegate feed tube and adjusted it to make the angle a bit larger, to raise the driver side wastegate to better mirror the passenger side.  

Also mocked up the Precision 64mm BOV just to see where/how it would fit since it's so huge. I think on the passenger side looks actually okay, matches the look of the DBW throttlebody servo. With the BOV on the passenger side it also helps fill some of the void on the passenger side, since I've made everything symmetric but the symmetry plane isn't actually in the middle of the engine. Look at the pre-turbo piping relative to the heads. The turbo's themselves are perfectly symmetric to the engine and their respective piping ended up looking visually correct and not wonky, but it just happened to not be perfectly symmetric to the engine.. oh well.

Didn't get too far on disassembling the front end. Not at the point of being able to make a cardboard mockup intercooler, but did enough to start mulling over the piping etc in my head.

Might be hard to see the silver lines on the rad support, but that's how wide I'm going to start trimming the core support. It'll be 1/2" wider than the intercooler on both sides, which will let me jam the intercooler close to the radiator but not touching, and the rad support will be completely outside of the intercooler. I think I'll use some rubber insulation of some type to seal the backside of the intercooler to the front side of the radiator but not allow heat transfer from radiator to intercooler.
