In the pics, the trans wasn't bolted up, so we wanted to to do that first, then fit the headers. The engine was just sitting on the mounts (bolts in, with a couple nuts on to keep it relatively steady). I'm sure it will have to be lifted off the mounts some, esp on the drivers side. On these engines, the torque convertor bolts are accessed through a hole in the bellhousing (for the starter), so I was reluctant to install the headers ahead of time. I imagine clearance will be tight with the 1 7/8 tubes.
I'm about to lock up the shop tonight, after a long day! I got here at 7am, and we just finished up. Thanks to Chris (C5Golfguy) and Clark for sticking it out today, in the near 100 degree heat and high humidity, to really make some progress.
The GMPP harness is set up for an older style oil pressure sending unit (the small plug one at the top), and the LS376/480 comes with the larger, late Corvette style. We switched this out rather than alter the harness.
The transmission cooler line fittings that were supposed to fit...and didn't. We wound up buying a pair of 9/16-18 to AN6 steel adapter fittings from a local hydraulic supply for $2 each (rather than the $27.30 Summit gets for the ones that don't fit).
The Vette filter/regulator assembly with all the AN-6 Russell quick disconnect fittings. Hadn't mounted it yet.
The tank, back in all clean and painted, with the modified GN sending unit/pump assembly inside. Something I forgot to photograph beforehand! Its set up with AN fittings for the feed, return, and vent, all plumbed in -6 AN.
The assembled rear brakes:
Looks like Anacondas are swarming the LS3! The headers fit well, but took some finagling to get in.
Goodnight folks!
