Don't get me wrong. I think these motors are awesome. Here is what I got done last night. She is sitting in her new home. Still need to get it slid back a touch and get the trans x member back in but I shoe horned it in there by myself last night. It fought me all the way but finally it popped in.

Did you get the motor mounts mounted in?
Any problems with clearance with the Dirty Dingo brackets you have?

by michiganlarry Thu Feb 28, 2013 9:52 am

Motor mounts are in and bolted. The oil pan is right up against the cross member but it should slide back 1/2 inch or so which should give me plenty of clearance. Probably wont get back out there till Saturday. I will post up some pics when done.

So the other night when I put the engine in it seemed like it went in hard. So I started checking it out yesterday. The oil pan was touching the crossmember on the passenger side so out it came. This is what I found.

And on the crossmember

The brake line had to be replaced. The decision was a $200 swap oil pan or notch the crossmember. I figured notching the crossmember would take me a couple hours and a hundred bucks an hour is pretty good pay. So I notched.

Cut a patch from some flat stock I had laying around. Welded and ground the welds.

Started on the down pipes. Need to rotate the drivers side and weld in O2 sensor bungs in both sides. Then weld on adaptors for existing exhaust sytem. I am trying not to cut up the exhaust so we can install headers at some point.

Waiting on the Holley alternator and ac bracket. Going to wrap up the exhaust tonight and start on the fuel system. Have an impalal gas tank and internal pump to install.

Is the 4L60e Trans just an extra heavy duty 700R4?

by dynchel Wed Mar 13, 2013 8:22 pm

I think the "e" designation means electronic. I don't think the 700 r4 was electronic.

by dragons_lair59 Thu Mar 14, 2013 10:23 am

the 4l60e trans is a little heavier duty and yes its electronic. also same with the 80le beind stronger yet and elecronic 200r4 and 700r4 non electronic. side note the early 700r4's have a alot of week parts i beleive by 87 they were fixed. how do i know 82 chevy 4x4 killed the tranny and every shop said case was weak from factory and even though had 2nd and 4th and reverse all parts would need replaced beacause as i was told just plane junk. said would be cheaper to go get newer case and rebuild or buy a new one

by 77mali Thu Mar 14, 2013 3:02 pm

Thanks. Looks like a good upgrade with the LS1.

Correct. The 700-R4 was later re-designated 4L60. When it became electronically controlled it was designated 4L60E.

Nice work there Larry........

by michiganlarry Sun Mar 17, 2013 6:07 pm

This weekends work. Started Saturday wrapping up the exhaust. Broke a stud off in the passenger side manifold so almost an hour wasted removing that. Hung the down pipes and then cut and welded pipes to connect to old exhaust system.

ls1 swap in my sons 75 - Page 2 IMAG0854_zpsa5370691

Once the exhaust was done I moved on to the gas tank. The old tank came out without to much effort
ls1 swap in my sons 75 - Page 2 IMAG0855_zps522ade89

and I starting installing the new fuel pump / sending unit into the 95 caprice tank
ls1 swap in my sons 75 - Page 2 IMAG0857_zps13e16220

I then realized that the junk yard did not include the lock ring with the tank. Grrrrrrr. Done for the night. Found one at Rock Auto and ordered the $6 part that is holding up that part of the project. That is the worst part for me. I hate waiting for parts. This morning I went out and lit the woodstove and came back in the house for coffee for an hour. Laid out the new harness and familiarized myself with the basic layout.
ls1 swap in my sons 75 - Page 2 IMAG0861_zps1abc9413

ls1 swap in my sons 75 - Page 2 IMAG0861_zps1abc9413

Next I found a good spot for the harness to go through the firewall and cut a 2" hole.
ls1 swap in my sons 75 - Page 2 IMAG0858_zpsb543eea1

The harness was fed through the hole from the inside and the rubber sealing grommit was installed. Then I fed the harness up behind the passenger side head and layed it on the engine
ls1 swap in my sons 75 - Page 2 IMAG0862_zps2ffb64b4

ls1 swap in my sons 75 - Page 2 IMAG0862_zps2ffb64b4

Then I started connecting the harness to the engine.

I found this empty connector the 2 pin one on the right. Not sure what its for.
ls1 swap in my sons 75 - Page 2 IMAG0870_zpsb8a80e11

Inside the car I removed the glove box and there is all kind of room above it for the pcm. Should make a nice neat install.

Post removed.

by dynchel Sun Mar 17, 2013 10:31 pm

That looks like a posi to me. I've never seen that "S" spring or the four clutches on a open rear end. Shocked

unless I'm missing something, i think you are wrong.

by pila Sun Mar 17, 2013 10:34 pm

I'm not a posi guy, but if that's not a posi, what are the edges of what looks like clutch discs on the right side in the picture ??
I've never had a posi rear end, so I'm still learning ! Very Happy

Part of the carrier bearing mount ?

by 1973montec Sun Mar 17, 2013 10:43 pm

It spins both wheels. If you rotate the yoke both wheels go the same way. Ive seen it. The 73 monte that chris had it in would spin both tires what seemed like forever. Just sayin.

by G3NUT Sun Mar 17, 2013 11:01 pm

The 2 pin connector to the right of the map sensor is the oil pressure sender.

by michiganlarry Mon Mar 18, 2013 7:32 am

I was wrong and am sorry.

I stand corrected.

Should of thunk before you blurted. Maybe you could of said "i've never seen a posi that looked like that" but who am i to judge.

When i bought the monte i did not know that a posi was under it. I took the rear cover off because it looked different than others ive had. When i looked inside, it looked different to. So i thought (guessed) maybe it was a posi. So i pulled it and kept it. I already knew what an OPEN rear end looked like. But never saw a posi before. As the saying goes"you learn something everyday".

Before your rant, did you look at the link i posted at the bottom? I tried to help. Have a good day

by michiganlarry Mon Mar 18, 2013 11:30 am

Never meant to upset anyone. I am truly sorry if I did.

I did see the link and am grateful for your help. Thank you.

by 1973montec Mon Mar 18, 2013 5:28 pm

No harm

by 1973 454 MONTE Mon Mar 18, 2013 9:19 pm

ive been holding on to this rear-end for years. if someone told me it was not a posi,than its taking up space and it would have to of been gone a long time ago.

just seemed like you were telling me i did not know what i had. on a side note,i would of loved to sell you an open rearend if you thought it looked like a posi.... Wink
