Gonna bounce early this afternoon to get some more parts! Picked up a fuel injection release tool yesterday, so we'll see what happens!

Re: Old Yeller's new heart-5.3/4l60 swap!
 

Nice day to get out early. Hope you're able to make some progress.

Re: Old Yeller's new heart-5.3/4l60 swap!
 

So, got off work early on a very pretty day and ran by HF for more tools for the jump box, then hit the yards! Long story short, got the bolts for the motor mounts, some other misc stuff, and this-

Yes that's the whole fuel system from a '00 Silvy, in one piece.

Sweet score on the fuel lines! How much re-work ya think to get that into Yeller? Suppose it's metric sized tubing??

Re: Old Yeller's new heart-5.3/4l60 swap!
 

Well, Saturday was a bust....kinda. Been having some weather, MX track was supposed to be open on Sat., but we were on hold due to rain. So, I waded into the rollaways and de-crapped and put stuff into boxed storage, and re-organized. MUUUCH better.:metal:

Then, we were bored. so, Yeller's longtime followers will note we bought a HF blast cabinet, and got so damn busy we never assembled it! So, The Kid got all motivated and he and I got busy after dinner and got it assembled. Till 1045 last night. The whole time I was hacked off at myself for not getting more off the gift of the Silverado that I found. Soooo...

Got up and was at PNP when they opened. Got unmolested Trans lines, Torque convertor bolts, and other odds and ends and clips. Took right at an hour. You really get your money's worth out of Sunday when you get up early and get movin'! Hopin' to get cleaned up and painted this week. Gratuitous pic for John-

Re: Old Yeller's new heart-5.3/4l60 swap!
 

I know, I gotta get some aluminum oxide! Had to do some runnin last night, then actually made a very tasty dinner at home (shock) then did a bit of Sprint car work.

Re: Old Yeller's new heart-5.3/4l60 swap!
 

Completely Unrelated (but joyous) Update!

Longtime followers may remember that we sent the radio out to have a bunch of groovy updates done to it. Supa custom and stuff... It worked grrreat, 'til you started the motor. BRRRRRRRRRRRR.... not turbo weeeee, BRRRRRRRR. So, I have a friend here at work that's a former electronics tech and a car guy and I conned him into coming over with his super groovy meters and stuff. So, we changed some ignition stuff, nuthin'. Changed some wiring stuff, nuthin'. Started pawing up under the dash, dead quiet. Then BRRRRRRR. "What'd you do?" "I don't know!" "Do it again!" All he did was squeeze the radio chassis' top. Hmmm. So we tore it all out.

Near as we can figure, there's a circuit board vertically installed with a bit of room between the top of the board and the insulating plastic sheet on the stock chassis, and it came loose from whatever socket it plugs into during shipping. Leading to loose connection, leading to BRRRRRRRRR. Took the lid off, poked and prodded, plugged it in, dead silent. Fired it up, dead silent. Plugged the Ipod in, silent. Hooked up the amplifier, dead silent.

Oh, and after months of fighting and desperation with ignition problems and carb problems, Neighbor Jay got the Sprint car running running last night. Not fire up and sputter and rev and hunt and burp and fart, but run smoothly. We're all pretty excited. Looks like we're goin' racin' this weekend!

So hey, it would appear that we finally fixed at least one of the mystery ills on this damn truck. Not LS related, but even a small victory is a victory, right?

Re: Old Yeller's new heart-5.3/4l60 swap!
 

Congrats on finding your bug and fixing it. :metal:

Re: Old Yeller's new heart-5.3/4l60 swap!
 

Thanks, ran out to Ryan's and picked up the paint today. Maybe some progress this weekend.

Re: Old Yeller's new heart-5.3/4l60 swap!
 

Cool you got the buzzin sorted out! Rock on :metal:

Re: Old Yeller's new heart-5.3/4l60 swap!
 

Thats crazy.

Re: Old Yeller's new heart-5.3/4l60 swap!
 

Tell me about it. This is the kinda stuff that happens all the time 'round here.

Re: Old Yeller's new heart-5.3/4l60 swap!
 

So, whadda ya gonna do with the 300+ ground straps Vern rounded up at the P&P?

Re: Old Yeller's new heart-5.3/4l60 swap!
 

LOL! Lots of 'em are already on! Everybody kept saying "more grounds, check your grounds, grounds, grounds, grounds." Well, by God, it's grounded now! LS's need a ton of grounds anyway.

Re: Old Yeller's new heart-5.3/4l60 swap!
 

Well???? Pics of painted engine? :jest:

Re: Old Yeller's new heart-5.3/4l60 swap!
 

LOL! Pics of me not at baseball/mx track/working on Sprint car/working on MX bikes/Repairing deck roof before 1.5" of rain comes (that was last night)? You're right though. Mostly, I need pics of me off my considerable ass and takin' care of bidness! In other news, we broke 3, count 'em, 3, bikes at the MX track on Sunday. Which reminds me, I gotta call and source a tire. And get a carb kit for the mower we just put a head gasket in. It's like whack-a-mole 'round here!

Re: Old Yeller's new heart-5.3/4l60 swap!
 

Ahhh, whack-a-mole! That's your style isn't it? "Like you're killin snakes" somebody once said to me :lol:

Think you've got the punch-list pretty well set or are we still figgerin? Clip coming off?

Re: Old Yeller's new heart-5.3/4l60 swap!
 

I think we're just gonna wind up pulling the hood and pass fender. I'm not thrilled with the fit of the pass. door (even though I hung and fit it twice in-process) so I gotta fix that. Plus Boppa wants A/C, so we're gonna need access for that. I'm stone tied up through Sunday, but opening up after that, so we'll see. I saw a couple neat ideers for fuel systems I'm currently researching, we'll see. I have plenty of lines and whatnot now, got Trans lines and a factory cooler now. I have both colors of motor paint, I have the motormount shells, so I just gotta clear decks and these sickles fixed and get after it.

Re: Old Yeller's new heart-5.3/4l60 swap!
 

looking GOOD! I'm following your thread as I am pulling the trigger on mine shortly. have one waiting at the yard and now looking for all the incedentals to install it i.e. manifolds ( TBSS) oil pan (CTS-V) etc. If you have any good thread with parts lists do share :)

Re: Old Yeller's new heart-5.3/4l60 swap!
 

Thanks! The best pan deal is the Hummer H3/GM "Hot Rod" pan, almost as shallow and a lot cheaper. 175 ish as a full kit from GM. We're having ours shortened by a very generous and talented fellow we all know. A superb lo-buck thread is here-

Re: Old Yeller's new heart-5.3/4l60 swap!
 

Pan was delivered to me last night via Northland Pony Express and surgery began today. Chip wanted ~2" removed from the sump parallel to the bottom plane. So first thing was to mark an OH $#!% line around the perimeter as a guide. I then set it up in the mill and leveled the bottom using 1-2-3 blocks and some shims. I rigged up a Controx slitting saw in an arbor, set the height I needed, held my breath and punched the button. My little mill is too small to make a full perimeter cut without moving the part. So I cut about 2/3 of the front and back of the sump and all of one side. Then turned it around and set it up again on the blocks facing the opposite direction. Sliced the rest of it and voila! ...two chunks. Piece of cake.

I had a half dozen pieces of 1/4" billet aluminum plate in the scrap bin, so I dug one out, set it on the pan and marked a line around the edge of the sump. Used that line to rough in the shape of the plate with the bandsaw. Chip and I originally talked about taking out a section and welding the bottom of the sump back on, but due to the shapes involved, that's not practical. It would also be very hard to get the 2" of clearance we need. So a flat plate is the best approach IMO. After getting the approximate shape, it was back to the mill where I trimmed the edges to allow about an .080" step for welding. I'll weld both the outside and inside for strength and leak prevention.

Tomorrow I'll notch the plate and the side of the sump for the drain plug I sawed out of the leftover bottom piece. Chip sent me a link to a Digital Corvette site where a friend of a forum member named nitrovette had done this and it looked great. I'm all about shamelessly plagiarizing good ideas. Stay tuned!

Nice work!

Vic is a baaaaad man. That looks awesome! Thanks so much! This is gonna be so cool!

Re: Old Yeller's new heart-5.3/4l60 swap!
 

In other news, I've been gathering a few more odds and ends, and plannin' and schemin' on a fuel system. I believe I've formulated a plan, we'll see how it works out. Hoping for big progress soon!

Re: Old Yeller's new heart-5.3/4l60 swap!
 

That's going to be a trick piece. Nice job on that guys!

Re: Old Yeller's new heart-5.3/4l60 swap!
 

Not me-all Vic!

Re: Old Yeller's new heart-5.3/4l60 swap!
 

Finished trimming the oil drain bung and saddled it into the side and bottom of the pan. Similar to the factory setup, the bottom of the threaded hole is down far enough to facilitate oil drainage. Welding cast aluminum to billet is usually a grungy process thanks to the impurities in the casting. However, the GM part is fairly good quality which helped a lot. I also used the bead blaster to clean inside and out where I'd be running weld.

After the bottom plate cooled, I set up the drain plug for welding. You may notice I chose to install the drain in the side of the pan instead of the rear. It appeared that, thanks to the 2" chop, a rear facing drain would have made it impossible to remove the plug. So it went into the side. Used a spacer to stand it off the side of the pan and provide a lip for the weld. After finishing the outside, I flipped the pan over and welded the bung from the inside also. I'd planned to weld around the perimeter from the inside as well, but I happened to look down at the floor and coolant was puddled below the TIG. One of the water cooling lines had sprung a leak, so I called it a night.

Re: Old Yeller's new heart-5.3/4l60 swap!
 

That's the sexiest oil pan mod I've ever seen. I wish I could that to my oil pan. I would pay for that in a heart beat. Question, how will adjust the dip stick and oil pick up tube?

Re: Old Yeller's new heart-5.3/4l60 swap!
 

That's a lotta work!! Looks great though. I went with a CTSV pan and pieces/parts myself...$175ish

Re: Old Yeller's new heart-5.3/4l60 swap!
 

I've shortened a dipstick in the past by cutting it, overlapping it by the amount I need and gluing it together with JB Weld. I then heat a piece of shrink tubing over the glued section to make it easier to slip past any tight spots.

As for the oil pickup tube ...don't know yet. I have it my possession, but I can tell by looking that the way it's angled, it will be a real test to maintain the mounting points and still raise the pickup screen two inches. I might need to get Chip involved as it may be best to section it with it installed. Sometimes it takes a 3D view to turn the light bulb on.

Re: Old Yeller's new heart-5.3/4l60 swap!
 

OOOOOOWEEEEEE that's cool! Man, thanks a lot. The two feet share a common datum that is 1/2"-3/4"ish below the pan rail. I can go home and measure tonight. Picking up truck #2 tonight right off, but I'll be home later in the evenin'. We'll see what's happenin'. Thanks again, this is terrific.

Re: Old Yeller's new heart-5.3/4l60 swap!
 

With the easy part out of the way, next up was the pickup tube. Started by fixturing up the tube on a plate used for a long ago project. I knew it would go well when two of the threaded holes lined up perfectly with the tabs on the tube. I marked reference lines around the tabs and parallel to the long tube and set up a height reference made from welding rod. With everything marked, I took it apart and started cutting. Oh, I forgot to mention the part where I stared at the setup for about an hour before making that first cut. There are three cuts and much as I hate to admit, all three are mitered very slightly. Normally I'd cut square to tubing, but over such a short run and with the limited amount of curved tube I had, it was the only way to make it work.

I mocked up the screen to see what I needed and filled in the gaps with tubing. With the pieces tacked or held together with magnets, I fit the pan over it to see how close I was. Chip had given me the mount dimensions on the block, so I know the screen will actually fit closer to the bottom when assembled. After checking the fit, I bent and tacked the sectioned leg brace to the tube. All that's left to do is fit it to the engine block and recheck the clearances. For that, I'll use several small pieces of modeling clay on the bottom of the screen covered with some plastic wrap. Setting the pan down on the rails will squeeze the bits of clay and tell where we might need to adjust. For now, it's only tacked together so it will be easy to fix if needed.

Re: Old Yeller's new heart-5.3/4l60 swap!
 

Just a few more shots of the pan after final welding and cleanup. I let it sit overnight with solvent up to the oil sensor hole and it didn't leak a drop. I did run a bead around the inside ...more for strength than anything else. Not sure it would survive being high centered on a stump, but I'm guessing that's not likely. ;)
