Pre-LS swap questions

[Root2812]

Angryman, thanks for the info. I'll look forward to seeing your project come along.

Today I made a few more steps forward. I got the motor out of the trailer and onto an engine cart. I just picked up the $50 cart and northern tool because I'll take it to my dad's shop to do most of the work to the motor. I just needed something so I could move it around in my garage. I took the wiring harness off so I think that is where I will spend my winter. I spent most of my savings on the motor and the intake I got today.

I purchased an LS6 intake off of a ZO6 Corvette. It was complete with throttle body, fuel rails, and injectors for $400. I'm happy. I can't wait to get it on the motor but I want to replace all the seals and all the gaskets in the motor first. This is exciting.

Man it looks like several of us are going to have winter projects to get done.

I would love to have my truck done by next summer so I could drive it home to visit my parents in northern MN and then head on down to back to the 50's fest at the state fair. Will see how much the 5 month year old cooperates and how much work on the truck the wife will let me do!

[Root2812]

Where in Northern MN? I plan to take mine to back to the 50's next year. I missed this year with brake issues.

Hey guys,

So today I picked up what is supposed to be the exhaust manifolds from a C5 corvette. I was told by forum members that the corvette manifolds would clear my frame so when these came up on CL I bought them. By looking can you guys confirm they are the right ones? It looks like the ones I see online.

My next question is what are these two holes on the exhaust? I assume the lower one is the O2 sensor but I am not sure. I looked at my truck manifolds and they didn't have either of these holes. I only gave $75 for the pair so I'm not heavily invested but I hope they are the ones I needs.

Thanks

[Jonboy]

The upper one looks like it was an EGR tube, and the lower one should be for the O2 sensor.

[Angryman117]

The smaller holes up top are for a EGR system. I am going to block those off on mine. The lower holes are for O2 sensors, you will need them if you plan to run EFI. Your manifold look slightly different than mine, but look like they should still work.

Here is a picture of my passenger side manifold.

[Root2812]

Well my LS6 intake arrived today. Its broken. The box was beat to hell and looks like it got dropped right on the back of the manifold. The part with the MAP sensor and vacuum ports got pushed into the intake and cracked around the circle. I don't know if it can be fixed or not.

I sent pictures to the seller and he is sending me another one so I hope that one arrives in one piece. Either way he doesn't want me to send this one back. Do any of your guys have experience fixing these plastic intakes?

Maybe rough / scar the area up and use some 2 part epoxy?

That's one of the things I've read people doing. Apparently this type of plastic is really hard to bond back together. I would like to find a professional plastic welder if I can .

More trouble than it's worth

Hey guys,

So this weekend was supposed to be the weekend of progress on getting the motor all cleaned up and what not. Unfortunately my 2000 GMC Jimmy decided to suffer from the all too common bad injector spider. I ended up spending my Saturday replacing that spider with the upgraded Multiport FI system.

Anyhow, my new intake did arrive and was in good condition. The guy I got it from didn't ask me to send the broke one back so now I have 2 sets of fuel rails, throttle bodies, and injectors. Spare parts may be useful later.

I also have been giving some thought to what has been said here by all of you and I am going to go with the 4l60e instead of the 700r4 I already have. It came down to easy of hook up with out having to deal with a tv cable and the fact that by they time I buy the adapter kit and tv cable I'm almost to the cost of the 4l60e. I just gave the 700r4 to my dad. Its going to go in a 57 bel-air behind a 283.

So here is a question. I have read that there are many differences in the 4l60e's. Could I run one that came out of a 2002 with a 4.8 when my motor is a 2000 5.3? I think I could but I want to check with you guys first. A local guy has that tranny in 2wd with 130,000 for $400. I can get him to come down. Up here in the north the 2wd trannys are harder to come by because most guys buy 4x4 trucks.

Thanks

That transmission will work no problem. If it was from a car you would have to change the tail housings but there is no difference between a 00 and 02 2wd transmission. Good luck with the build! Can't wait to see more progress!

huh?
You would only need to change the tail shaft housing if it was a 4wd tranny, the 2wd tranny is fine as-is. The other tailshaft change was switching to a 6bolt talshaft housing for the 1998 revamp. That would only apply if he was trying to use an old 4l60e, which would also have a 300mm shaft, different planetary etc etc.

and no car ever had a 4.8 or 5.3

If you re-read my post I clearly stated there is no difference between a 00-02 2wd transmission. I should have been more clear and was just stating a fact the if the trans came from a car, more specifically an f-body, you would have to change the tail housing.

oh and the 06-07 monte carlo ss, 05-08 Grand Prix GXP, 06-09 Impala SS, and 08-09 Buick lacrosse had a 5.3. jus sayin.

torque arm brackets can be added without switching the tailshaft housing, and none of the cars you listed used a 60e.

First things first. Before I can stab the motor into the truck I needed some front suspension and boxed frame rails to weld motor mounts too. My complete hub to hub kit from Fatman fabrications will be here soon. I'll post pics when I get it in.

Would like to know how you feel about this front end, during installation, etc. Have a friend that is thinking about one also...Jim

Jim,
I really liked the quality of the fat man kit. The only thing I'd change are the instructions. They sucked. They have good instructions for locating and welding the cross member in but after that nothing good. I've never put on A-arms, spindles, etc so I was expecting to see torque specs or a list of what bolt goes where. Nope. I figured it out but it was a little disappointing. But the instructions are temporary, the parts were really nice quality and the customer service has been great so far.

If you are still looking, we also make a bolt-in aluminum crossflow radiator for the LS conversions, with the correct inlet and outlet, both on the passenger side, along with the steam port and trans cooler for no additional cost. They are USA made, by hand, and fully TIG welded with no plastic or epoxy. Forum member discounted price is $425. Let me know if you have questions or would like to order one. We are also a supporting vendor on this site.

I'll keep you in mind when I get to that phase of the project. I still need to finish my suspension before I get to dropping the motor in.

He did not have a listing for the AD trucks in his site, looked like it stopped at 1955, Is he making one for you?

I haven't ordered a radiator yet. He posted saying they make one but I haven't gotten that far. I'm going to wait until I have the motor mounted before I start thinking about a radiator. I'll probably go with a Champion anyway since they have good reviews here on the forum and are only around $200.

We updated our site today for the new radiators for the 47-54 models, and we'll be making a new post in the classifieds. The customer we built the prototype for had a GMC, so the mounts for the unit in the pictures are about 1.5" closer to the engine than the Chevy version will be.





Here are some installed pictures (the first two are showing the unit in a GMC cradle, and the third was sitting in front of a Chevy version):
