    Howdy,

    I'll admit to not having enough time to really go into the details of what I've done and what's left but here are the pictures with the engine "hard mounted" but no transcrossmember and I can't believe how short of bolts are needed to hold the water pump pulley on, 5/16NF24 x 1/2's! I could only find 3/4in so I'm going to have to get a nut or something and cut them down.

    Basic run down of stuff holding it in/making it fit:
    Motor Mounts, Thanks to HRPartsnstuff for a You-Build-It version of thier G-body "Street" Second Gen motor mounts. They also sent a set of thier TTA side plates but the G-body ones fit better so I used them and welded the lower tubes to the frame with 3/16in plate spacers.
    Oil Pan, Its a custom cut down early 300 pan I think off of a '64 LeSabre. I cut the nose off the pan and cut 2 cylinders worth out of the front then rewelded the nose back on and redrilled it for the V6 front bolts. I then fitted it with a slightly modified Turbo6 baffle though it leaves some to be desired on rear wall fit. I also had to cut 3/4in out of the middle of the horizontal run of the oil pickup tube to get it to clear the relocated sump on the 300 pan.
    I also had to cut one of the ears off of the surpentine bracket and relocate the engine and trans about 3.5in forward to get the compressor to clear the upper A-arm on the drivers side. The #1 spark plug hole is still pretty much even with the spindle axis.

    Ask Questions, make comments (other than comentary about why I picked this engine for the car), and enjoy the pictures I have.

    You are a true maverick! Great to see some progress on the Great White Turbo Riv.

    Motor:
    Its an 8484 4.1L block out of an '84 Electra bored to 3.995in (0.030in over) with an Eagle stock 3.400in stroke 4340 forged crank, K1 stock replacement forged rods, and custom Diamond forged pistons. The cam is a Comp 212/212 roller conversion with T&D 1.65 roller rockers. The heads are Champion CNC Iron's and the intake is for now a stock unit though I'll be getting a ported unit and a 70mm TB after I get it running with a stock turbo. The headers are Poston steel units because my fancy Kenne-Bell/ATR's wouldn't clear the upper A-arm on the passengers side without fabrication so I sold them. Right now the turbo is a dumby exhaust housing so I can run it NA to sort out the EFI issues before risking the expensive parts with boost.

    The front cover is hybrid between a Stage II drysump racing unit and a Series II gerotor setup which means my oil filter has to be external and I've blocked off the oil feed passage in the face of the block and its now feeding through the old Oil Pressure port under the passengers cylinder bank. Its driven by a cut down lower timing gear off of a Series II V6 and the crank pulley is shaved down to match but still sticks 1/2in out farther to fit the Series II crank sensor.
    This brings me to the EFI system, which is a Series II L67 Supercharged 3800 system. Amazingly its largely just an evolution of the original 3.8L LC2 T-Type EFI system and the sensors have not really been a worry and since its a non emmissions car I can eliminate all that mess and I'm sticking with an SP400 at the moment so no transmission stuff either beyond the VSS. Going to get busy in 2 weeks getting the harness cut and fit to size. Goal is a running car by new years.
