So, i recently picked up a 2001 ss camaro 6 speed that hydrolocked, wedged the internals tried to spin with plugs out.
Today I was able to pick up a LR4 out of a 2005 silverado with 115k on craigslist for $400 with everything accessories computer and harness owner states it ran without no problems but truck got wrecked.

I'm just trying to swap the engine into the camaro and run it with that lr4. the thing is i wont be able to do anything till i get back 3 weeks from today (vacation). So, i can actually think about options of either just dropping the lr4 into the camaro with swapping the ls6 intake and camaro accessories. I have hp tuners and will be switching over the tables from the donor to the camaro ecu.

I'm debating if i should i take out the 241 ls1 head and put it into the lr4 replacing the 862 and swapping ls1 cam into it or should i just keep it simple and just drop the donor and just swap the intake and accessories and call it a day and ride it till it breaks while i figure it out and build the original motor that im taking out.

Any suggestions are appreciated and I'm also not trying to spend too much money.

Planning for it to be a daily and since the LR4 can run on 87 octane i'll be happy I want a quick fix plus needs to pass smog every 2 years

Thanks again
Lou

 

Keep it simple. Swap the manifold, drill the alternator bracket hole in the driver's side "ear", and swap over the accessories. Slap on a set of long tubes, a decent Y-pipe, and an exhaust while it's out, and let it ride while you figure out the long term game. Otherwise, you'll be doing more work for no real gain. Additionally, I would swap the oil pan gasket and rear cover gaskets before stabbing the motor in. Considering the 2 year comment, and the uncertainty of how long it'll find a home in the car, I would think that you don't want to drop a motor in, spring a leak somewhere down the road, and have to drop the trans again. Just my $.02.

 

Sorry ahead of time for the ignorance. but what rear gasket covers are you referring about? Im doing the same swap and will do the same thing..

 

The rear cover that holds the main seal and retains the cam.

 

would this be it?

 

Yup! That's it!

 

cool deal. Do you think replacing the oil pump is a good idea also?

 

at minimum I would replace the lifters with ls7 lifters, pick up an ls6 oil pump which many vendors on here sell both and if you so choose run the ls6 cam if your planning on tearing it back out down the road and just run it for he time being. At least then you know the motor is reliable and can sell it for a little bit more then you paid for it

 

There are TWO LS6 cams; early and late .
Early specs- 204/211, .525/.525, 116LSA (Is also the LS2 cam)
Late specs- 204/218, .551/.547, 116LSA

The early one will give you a little better low end.

 

I've done this exact swap , (2002 706 headed LR4) into a beat up old 2002 z28 A4 that I initially bought for a parts car and I absolutely love it. Been daily driving it for two years now, not going to part it lol, I'm in love with my little engine that could.

I really wouldn't bother with headers right away as they really aren't worth as much on a little 293ci. I would however strongly recommend that you replace the stock cam with at least the stock LS1 cam (1721) or better as it will greatly extend the powerband and Rev range of the 4.8. Also replace the springs with some good ol LS6 springs while your in there. I've taken this exact setup to 6800+ hundreds of times without issue. Really the only other thing that you might want initially is a 4.10:1 rear gear to really help keep the engine up where it makes good power. You'll be surprised how hard it will run with just that.

 

I just RE-read your post. The 4.8 will drive just fine on 87 with the stock 01 5.7 tune. Ask me how I know lol. Yes you'll want to do a good wide band on it later but you really only need to drill the block for the alternator bracket and just swap long blocks.

 

I've taken this exact setup to 6800+ hundreds of times without issue.i dont understand are you talking about? the rpm?

also with the ls1 cam if i do it do you think i could i keep the oil pump and chain thats in the 2007 lr4. the hydrolock ls1 i plan on building over the years if its still build able i'll put it in my 67 camaro that has a different 99 ls1 with t56 .

so you're saying just swap the cam and ride it with the 01 ls1 t56 stock tune while running 87 with the ls6 intake will be just fine no need for me to swap tables cause i dont really want to burn credits on the hp tuners

thanks again

 

Leave the 862 heads on. Flow the same as 241 and better compression. 241 would be a downgrade

 

Also don't forget to check what reluctor wheel is on the crank. If its the 58x you will need to swap to the 24x wheel or buy the Lingenfelter conversion box to run the stock Camaro ecu.

 

What what about the cam? Should I swap it since I won't use that with my build do I need to change the oil pump and chain too or can I just keep the lr4 pump and chain and just slap the ls1 cam?

Thanks

 

leave the pump and chain, just swap the cam.

 

Send those 862 heads to Texas Speed and let them do their CNC and valve upgrade on them....

 

got the car running... driven it for almost 400 miles with new ls7 clutch, but before i got it to run i had issues.
wow so i basically just swapped the ls1 accessories and cam and took me about 7 days to do everything from dropping the k member getting the clutch to come in during the holiday rush from black friday and getting the car to start... super exited because wanted to drive the car beginning of December.but when i started lifters was all bad knocking like crazy so i cut it right away... and i remembered when i pulled the lr4 cam i didnt look at it cause it was dark and getting late when i pulled it... come to find out the were groves on the cam smh
so now i had a decision to make either drop the kmember again to pull the heads out; glad i ended up just pulling it from the top its was a mess and it was harder but again this is my first 4th gen dropping kmember and doing first time doing cam head swap ect kinda learning as i go. I believe i was also being cheap about the head bolts because i didnt want to buy them in the first place and assuming the $400 motor i bought was a steal but i guess why they pulled it in the first place. Luckily, i had the ls1 motor still down the st cause i gave it to a buddy he wanted the crank so gave him the whole motor one rod was bent and the block went through so no need for it. I went back and took out all the lifters and installed them in the lr4.
Now finally after 3 days pulling heads waiting for bolts and gasket to ship to me from summit got the car running, drive it for 100 miles then torque arm bracket bushing come out the tranny making rear end noises thinking its the rear end
i fix it then the dam radiator starts leaking crack somewhere man one thing after another with this car. I felt like this car was suppose to be an easy swap not a project like my 67, and 69 camaros that i dropped an ls1.

Right now its running great still breaking in the clutch, I just replaced the D window motor, new thermostat and radiator. i still need to change the crack windshield and tires soon.

I just want to thank everyone that helped out in the process of this car i got oh i forgot threw a code the other night also p0410 but i deleted it and hasnt come back on i hope it doesn't come back on cause i need to get the car smogged soon.

going to attach photos of those lifters i pulled after i first started the car

 

Not to sound like a huge d-bag; but why would you swap to a 4.8 without turbo? These things love boost!

 

Well done.

I just did something similar to a 5.3L (I was told it was a 4.8L when I bought it) we are using as a boost surrogate until the raunchy 4.8L is ready. Ported the stock 706 heads and oil pump, slammed in a used '01 LS1 cam and yellow beehives, and popped on a ported LS6 intake and 78mm throttle body. The only thing I am waiting on is the '01 Z06 cam sitting in my buddy's car - but, that can wait. When I get the 4.8L sorted, and if this 5.3L is still living it will be going in my wife's future auto-x 3rd Gen Camaro as a baby LS6.

For $250 and a few gaskets it owes me nothing.
