@@StationroadRatrods 2 years later anything you would change / everything work well for you? Getting ready to do this (gen 4 engine with gen 3 ecu and harness) appreciate your help
@teabag402 that’s a solid question! Everything worked out absolutely perfect with the conversion, never missed a beat. As for the engine itself, I didn’t have the oil pan baffled well enough and it put 3 rods out the block 😬 Here’s a first person view of how that happened lol czcams.com/video/lEmKjshpNz4/video.html
24 tooth reluctor on the crank, the different colored crank sensor, the Gen 3 Valley Cover with the cam sensor bore and ofc the ops, the plain timing cover or plugged off cam port on timing cover. Gen 3 knock sensors
Black crank sensor You actually can’t use the gen 3 cam sensor on these blocks, the hole isn’t in the block for it. You need to use the front cam sensor on the cover and the 1x front cam gear. Also, the gen 3 knock sensors won’t screw into the middle of the block but I’m sure you knew that. It’s easier to wire in the 2 wire gen 4 knock sensors and just use those. Everything else is good.
1) Did you have to change the crank gear or you did it just to do it? 2) so you put a gen 3 crank in a gen 4 block? 3) can I use that cloye kit on a 5.3 or is that only for a 6.0? 4) so you changed the crankshaft so you didn’t have to change the reluctor wheel? Thanks this is my second time watching this video to make sure. I have a gen 4 block that I want to use with a gen 3 harness. That’s why I’m asking.
1,2,4) I haven’t changed a crank reluctor before and I had a spare gen 3 crank that was in good shape so I just figured if I have to take it out anyway, it’ll be easier and faster to just bolt in the gen 3 crank. 3) that cloyes kit will bolt to any 3 bolt cam and work on every LS crank (that I know of, at least the truck engines) Ask any questions you like, I’m always around to help if I can. Good luck!
What I did with this engine was put in a gen 3 crank and the black (24x) crank sensor. The knock sensors was an issue, I didn’t have the wiring for a 2 wire that goes on the side of the block so I couldn’t use them at all. Since then I’ve found out that people drill and tap the correct size threads for the gen 3 (1 wire) knock sensors and screw then into the side of the block
To be honest it depends on what you’re looking to do. If you want a budget friendly engine swap and like simplicity, then 100% go for a gen 3 engine, they’re cheaper and are usually easier to swap, and simpler to tune. If you’re confident in your tuning (or can afford a tuner) then the gen 4 engine is great also. They’re essentially the same engine, just the gen 4 has more shit attached to it.
As far as I know you can’t use a 4x with a 24x crank, but I may be wrong. I did see a video somewhere where a guy showed something like that, and I thought it ran but I can’t remember what gears he was using. I though E38 pcm started in like 07 or 08? I’m not familiar with the corvette stuff.
@@StationroadRatrods Kens korner posted a video of him doing the swap on his 97 CAMARO with a Ls2 swap. He installed the 4x with the 24x reluctor. But he was also using a MSD box for his timing. My bad it’s a E40 on the 05 c6 come with the 24x/1x setup 06and up come with the e38
@@StationroadRatrods I’m switching over from the LS2 to a 427 sleeved LS3 while trying to keep the stock computer and harness. And keep it as DIY as can be 😂
I got a gen 4 engine in my trailblazer so all I do is change the timing gear and put the Gen 4 timing chain cover on with the sensor thing and that's all I need?
You’d actually need to change the crank also. The easiest way do this job is to buy a lingenfelter box. It changes the signal to match the gen 4 engine to a gen 3 pcm
@@StationroadRatrods I got a 2005 envoy Denali it says it's a gen 4 but it's using the same 24-time reluctor wheel as the gen 3 so I don't have to change the crank then?
Any 5.3 99-06 are the same. The block and heads is what you’re after so if you got a DBC engine, you could reuse your intake manifold and other parts. Try to get an 03-06 engine if you can, they have better pistons/rods, but 99-02 are good engines either way
@@StationroadRatrods thanks sir! I have a 79 Camaro I'm wanting to do an LS swap on, I'll subscribe to your channel ! So the earliest Ls,have a 24 tooth reluctor, and the later has an 80 something tooth
Sweet dude!! If you’re on Facebook check out my group, it’s called “station road rat rods CZcams” I and the other peoples there would love to check out your build!!
We changed a engine for a friend and it was a 07 Chevrolet silverado 5.3 aluminum block and the engine he bought was a iron block we bought the timing gear like you did and it runs but sounds like timing is off. Would it need to be tuned or something deleted? The top of the engine was different also the plate his teuck came with a plate that ran all the way across the engine and new engine didn't the 2 plugs in back of plate was on the aluminum block and the cast iron block plate ended before the 2 plugins. Dont know where he got the motor for his truck but it wasn't the same smh
If his truck is an 07, you’d want to use the same front gear that the 07 has. It would be a 4x cam gear instead of the 1x like I used here. I would think that’s not the issue, but maybe the crank sensor. Can you look at it (behind the starter) and see if it’s black or a tan/silver colour? The tan/silver one would be correct, the black sensor won’t work right
@@StationroadRatrods it was black. Both the 07 motor that came in truck and the motor we put in 06 Tahoe both 5.3 L have black ones in it. So we need the tan/siver? Thank you for answering my questions I also Liked and Subscribed.
The plugins on donor motor 06 Tahoe has two sensors on top of engine behind plate under intake original one had a 6 prong to the left of oil sensor and the 06 Tahoe has a 3 prong plugin so we didn't hook it up or couldn't lol. Would this be a problem also?
It’s odd that the engine you took out would have a black sensor. The plug behind the intake is going to be the active fuel management system. The iron block won’t have that, and you’ll need to have the pcm tuned to delete the AFM or the engine won’t run correctly
Depending on how you wire it yes, Absolutely. I used the little harness that plugs into the cam sensor which already has the pins repositioned. If you don’t want to use that harness, you’ll have to switch the pins
Do you mean to pull the crank gear off? I couldn’t get it at all with a puller, so I adapted lol. I’d imagine the crank sees a whole lot more force than that with the 12” heavy duty clutch and me popping the clutch in 2nd gear with 2 step 😅
Hey, so if you are only doing a VVT delete and staying with the 4x cam gear, you only need to tune VVT out of the pcm, you wouldn’t need the box. You only need that to change from 4x to 1x and vice versa
Man that’s a whole mess of different generations of parts haha. You’d run into issues with the gen 4 harness and the gen 3 throttle body, I don’t know if they’ll communicate. And I’m not sure about the 6l80 but didn’t that have a separate transmission control module?
Okay. I think the only part that would give you issues would be the gen 3 intake/throttle body. You’d be better off going with a gen 4 intake and throttle body (tbss style) because it flows better and it would just plug in and work. Everything else should cooperate just fine
So let's say someone didn't do the crank swap to the 24tooth. And we still have a 54x and 4x cam sprocket to put that gen 4 engine into a gen 3 vehicle do we still need to use the lingenfelter box? I'm assuming we do. I wasn't particularly wanting to break open the bottom end of the engine.

Did you end up having,injector problems from the air gap being to big between sensor and sprocket?
I didn’t have any cam sensor issues at all, this setup was used on the LS2 so it was all factory parts
I’m new at the ls deal. I have a chance to get a 2012 6.0 for a swap. Is a gen 3 a better way to go? Confused on choosing. Thanks for any help

Hopefully so. Did you use the harness that bolts to the front cover? Or just extend your harness and plug directly into the cam sensor?
pulling on the crank that direction by prying seems not a good idea if its on there much tighter than yours...
