Pre-LS swap questions

[Root2812]

So now that I decided to go with the 4l60e I'm in a predicament. I haven't been able to score a tranny yet but I want to get my suspension and motor mounts all welded in. Can I use the 700r4 for mock up or are they too different in shape? I won't weld the tranny cross member in but I want to have on there when I make the motor mounts so I can get a good idea of how/where to position the motor.

[Angryman117]

The 700R4 and 4L60E are very similar but the cross member on the 60 sits back about an inch or so than the 700. I know this cause I did what you were talking about doing. Thankfully the mounts I have are bolt in and not welded. I was also thinking about getting my drive shaft sized with the 700, good thing I didn't. I got a 99 4L60E from a suburban with the torque converter from a local salvage yard for about $300. How far are you from Hitterdal, MN? I got my engine from there, found on CL for about $550 with everything I need to make the engine run. I am sure they would have a couple of 60's laying around.

[Root2812]

Hitterdal is a long ways from here but there are a lot of yards around here. I just spent all my money on the suspension so I would like to use the tranny I have for the mock up and worry about buying one later.

I wasn't going to bolt or weld the tranny cross member in, I was thinking of just using some clamps to hold it in place while I set the engine mounts. The part I am concerned with is clearance to the firewall and floor so if they have a similar in height and bell housing shape then it will work. were they close enough for you?

[Angryman117]

What engine and transmission mounts are you using again?

[Root2812]

I was going to use these..

I am using the same transmission mount but different engine. Here is the link to the kit I am using. I don't remember exactly how much room I had but it was tight when I still had the cab on the frame. I had the engine about 2 inches from the cab, plus i do remember the transmission hitting the floor (what was left of it). I am going to put a small hump in anyway just to make sure I have plenty of room. Hope that helps!

Hey guys. Have any of you used these dirty dingo mounts?

I think I like the design and they look strong but I'd like to hear feedback before I drop that much money. Its either going to be those or these.

It looks like the Dirty Dingo mounts will have more flexibility and might be easier to install on my flat boxed frame rails.

thanks

DD mounts have been used alot! they allow for front to back movement if you need the room. great product too!

[Root2812]

Hey guys. I just wanted to share a quick update. I got my front suspension all welded in. Next I will start doing the motor and tranny installation. Slow and steady wins the race.

I pulled my frame donor truck into the shop and got to work.

From this




To this


I'm getting closer every day!

[Billett]

Keep up the good work!

[Root2812]

Thanks Billett.

This is my first build so its been fun, educational, and comical at times.

[Billett]

I hear that. This c10 has been my first major engine swap. Not something I'll forget soon!

[Root2812]

So progress continues. I got the front suspension all bolted on and I got a rear suspension ready to go in. I kept dragging my feet on getting a tranny but finally pulled the trigger this afternoon. I got a 2001 2wd 4l60e from a Silverado that had a 4.8L in it. The tranny has only 73,000 miles and cost $644 out the door. The price is good considering I didn't have a core to trade in and the 2wd trannys are not very common around here. I think this will work well with my 2000 5.3 and I think the 2000 wiring and PCM should be compatible. Anyone thing otherwise?

Below are some pics of the front IFS all finished.

[Clyde65]

01 trans and 00 motor? You good to go!

Do you know if your PCM is from the motor or was it sourced separately?

[Root2812]

It came from the same guy I got the motor from. He had a few PCMs on the shelf so its hard to say if it came from the same truck. It does have the right part number for a 2000 PCM and its got the right color connectors.

Did you confirm that the 700R4 case is different than a 4L60E case for the rear motor mount location?
We were going to use a 700R4 case for mock up but now I am concerned there will be different length question

After the guys on here told me they were different I didn't even pull the 700r4 from the donor so I couldn't measure. Its waiting in the donor for my dad to be ready to use it. I will have the 4l60e on Friday when I go to the salvage yard to pick it up and I can measure bell housing surface to tranny mount for you and you can compare to your 700r4 to see how much difference there is.

[Root2812]

Hey guys, I'm finally about to the part you've all been waiting for. I finished my suspension this weekend and by the end of the month I'll have the motor and tranny in. I just wanted to post up some pics so you know I'm still working and I also wanted to ask a question.

Pics first

Rear suspension is done


Chassis on the ground ( its level now but will have a rake when I get weight on the front)


And of course the tranny I told you all about.


So my question.... I set my pinion angle at 4 degrees up. The rear leaf kit wanted 5 degrees angle and I read 3 lots of places. What have you guys used? I asked this over in the 47-59 board but figured I might as well ask the LS guys too. I have the perches tacked in now so if I screwed it up I can still change my pinion angle.

[Root2812]

Well Finally this weekend, the engine found its home in between the frame rails! I haven't finished up the trans cross member yet but at least the engine is in.

I started by getting the tranny and engine mated together and up on the lift.


And I had put the Corvette LS6 exhaust manifolds (heat shields removed) on but I had to take them back off for clearance. Its really really tight!. I'll end up clearancing my frame boxing plates a little to make the exhaust clear.


I used the Dirty Dingo adjustable mounts and had to trim them down to fit but they worked great. The mounts came with 2 rubber isolators for each side but the pics from Dirty Dingo showed one between the mount halves. I assume the second is so the bolts will tighten evenly without distorting the first isolator. I think I'll move the second one to the nut side but for now I put it on top to take up the slack. The one that needs to be between the mounts is.


So after a days work here is what I have.



I have to pull everything apart for paint so this is just mocked up but man that engine looks huge on this tiny frame! Its going to be fun!

Since this old truck had such a small motor before I know front to back clearance will be tight but it will fit. I have everything within a half inch of where it needs to be and my slider mounts have 1 inch of adjustment left each way so I'll be good. It does look like a pusher fan is in my future.

Nice Radiator, and I am looking for a new rad. for my 55 1st series G M C!!!

[SparkyRnD]

That is the next one we want to prototype (send me a PM if you are interested)

So I have some minor updates and a few questions I hope you guys can help me with. I still haven't fired up my 5.3 but I decided to just do a rebuild on it anyway. It has 180,000 miles and I hate leaks so I was going to change all the gaskets and seals but since I am in there I might as well do bearings and rings. Then since its all apart I might as well send it to the machine shop for a quick hone and hot tank. Its amazing how things snowball on you. Aside from that I'm just about finished with the chassis and the engine and tranny are mounted. I also got a S&P MAF/air filter from a ls1tech board member for $220 that was never used and is the chrome one so I am happy about that. He said he spent $600 on it. I had only looked at the non-chrome one and that would have been over $300 so I got a good deal.

If you remember back a while, I had gotten an LS6 intake that came broken but was replaced so I had the broken one for free. I decided to try and fix it. I know the Nylon66 is a bastard and is nearly impossible to bond to with anything so I contacted a company that specializes in plastics and plastics epoxy. They had an epoxy made for thermoplastics (Nylon 66 is one) so I paid $30 for a tube to try. That stuff is stronger than I had ever imagined and it looks like it worked. I'll give you guys a more detailed write up after I test it out. Hell, if I can fix it for $30 and sell the other one I come out a head.

I'm also starting on my harness and I got in contact with Branden at LT1swap.com for my PCM flash.

So here are my questions. Since I am swapping the LS6 intake on to a 5.3 should I use the MAP that came from the truck or from the car intake? I have both, one is the black label and the other is blue.

Anyone know a good source for the injector pigtails for the LS6 injectors? Those are EV1 right? and the truck is EV6? or is it the other way around?

thanks

Any more info on the Epoxy for Nylon 66?

I should post the pictures that I have on my phone. The epoxy worked better than expected. What its going to come down to is if I was able to sand it smooth enough to get a good seal at the o-ring. Since I ran into trouble with my engine it will be longer until I can test it out. I'll post up the details from the stuff for you too. Once I get to test the intake and determine if my repair works I'll put together a how-to or something.
