This pic is a little outdated and not everything was hooked up yet. This was right after I got the engine in after I painted the engine bay. I will be installing a LS1 brake master cylinder and I just installed a flexible transmission dipstick. I'll be repainting the engine, again.
95 LT1, emissions removed, windshield wiper equipment removed, antifreeze overflow tank replaced with hidden aftermarket tank, battery relocated to rear trunk, alternator relocated down low, LT1 fans, LT1 radiator, modified LT1 radiator shroud, holes in the fenderwells welded/filled in, bulkhead wiring relocated, holes welded/filled in on the firewall, hole from bulkhead welded/filled in, pcm relocated to interior, LT1 wiring goes through big hole underneath of the heater core.
I can't resist a chance to show my engine. I also relocated my PCM. I extended 75 wires 4 feet and ran it through the factory hole in the inner fender area. The other pic is the car.

IGNORE the wrench... My coolant and squirt bottles are where my air filters used to be with the stock TPI setup so what you see here is my final. I tucked as much of the harness as I could underneath my upperplenum so you don't see them.
Ok AC, i am completely drooling over how yours looks right now... the contrast between the black and red makes it look so amazing, and then how clean it is...
Goldie, thanks for the comments. Nice engine you have going in yours. The biggest thing for me was obviously stripping down the bay and then painting it black instead of the stock red. Also, hid as many wires & wire looms as you can. Don't be afraid to lengthen wires so you can "snake" them around differently. I think I lengthened about 15-20 leads in my engine bays harness so I could do things different. Everything from moving the knock sensor to the drivers side of the block to starter leads etc. When my upper plenum comes off you almost cant see the intake because a majority of my engines harness is there. Look in the third row down of pictures in my album and you'll see what I did. http://s6.photobucket.com/albums/y205/AC1LE/
Yhea, you can tell in the first picture that we have painted the left side of the engine bay, couldnt get to the right because there was so much in the way, hopefully we can get to that some time this weekend. and then maybe it will look better. If all goes well we will be moving into a house soon with a 1500 sqft shop so i dont have to drive 20 min just to work on my car anymore.
* If you knoiw that song than your getting old ! - Anyone remember that movie ??
I like the silver/red when putting a motor together. If the timing was different than the car would be exterior color in the engine bay - but I put the motor in before I had it painted. I don't care for cars that seem to have a clean motor and black "everything" else. The details are easier to see when they are not all the same color.
Here's a stock 305ci in my 86: ( this car is primer black )

My Wife tells me that Black/ Silver/ Red are the only colors that I ever wear. I think it's because all my cloths were bought to match my Earnhardt hat !
Colors...isn't that the movie with Bill Murray when he is the army? Wasn't it called "colors" or something like that? Anyway, Here's mine as it sits now:

If ypu want to see the pic with all the pulleys and other attachments someone will have to explain how to shrink pics. Or why if I have a pic in another thread why i cant load it here. Anyway VERY NICE GENTS.
86TA, wow, that really nice too. I've never seen it before. I'm curious to find out part numbers and how you connected SS hose to the heater in/outs..?
That was "Stripes" !! "Colors" was Robert Duval and Sean Pen as cops against Bloods and Crypts - Colors.
Not many people go with a light color in the engine bay,........ I think the light color is better than the dark colors because the engine bay is so dark to begin with. Just my !

thats a really clean setup.
are those the J&M mounts? i didnt realize they "stuck up" like they do.
you do need a molded upper hose. that universal has to go.

thanks
I soldered 90 degree copper fittings onto the heater core. one was 5/8 OD the other was 3/4 OD. I set them at about a 45 degree angle facing down so they both straddle the ground stud on the firewall that hold on the heater box. then its just straight 1/2npt to 10an fittings and 45 degree swivel hose ends. And it all JUST fits behind the valve cover

they do stick up, they worked well, but i never did like the sticking up part. They are off the car now, i went to coilovers so i have the spohn fabricated upper mounts now. I was thinking about AN for the upper radiator hose, i would just have to get an adapter welded to the radiator

if you do go with a AN top hose, id recomend running the black braided hose.
the stainless lines look good, but with a large one, it might look a lil too busy for how clean you have it.
Didn't get the chance to put the distributer cover back on (which really cleans things up a bit in my opinion) but this'll give you an idea.
I'll be relocating the heater control valve once the weather gets a bit warmer outside and routing the plug wires underneath the headers to clean things up.
I don't want to stray too far from the factory look 'cause I think these TPI motors are the best looking motors GM's ever put out
My most recent pic with an addition of a 2004 GTO cold air. I still need to add a 40 degree tube so I can put the filter block on to keep hot air off of the filter.
