Im sure this has been asked before but all I could find was 4.8 to 6.0 swap threads. I found a 70k mile complete LS1 for $750 that I want to put in my truck(ecsb 4.8). If I just use the ls1 long block will I need buy any swap parts (other than a new tune)or will all of my 4.8 stuff bolt up.
I am planning on a cam(not sure witch one yet) and stall(probrbly circle D,GM 278mm HP 4L60E LS Torque Converter) while Im doing the swap also.
TIA for any input
if its complete,why not just drop the entire thing in?
but yes,your 4.8 stuff will bolt up
swap over your accessories, oil pan and tube and tray, intake fuel setup. Then plug it all in and go.
Thanks. How much of a pain would it be to use the LS1 intake and would it be better than the truck intake?
Will my starter and flexplate/flywheel work?
When I order my convertor, do I order one for my truck or for the LS1?
Sorry about all the questions but this is my first non-Mustang project.
When I start ordering parts I will post what I have to make sure I have everything. I will be doing the swap 100 miles from home and Im not sure what kind of parts stores they have out there.
Thanks again for the help
The ls1 intake is less superior flowing than say a ls6 or fast intake, not many people run them if any. Also since the will be in a truck you most likely want to run the truck intake because the downside to the car intake even though you gain top end, you loose a decent amount of torque which never helps a fullsize truck.
your starter and flex plate will swap over.
Order a converter for the truck tranny.
Will my 4.8 inhectors be enough for a cammed Ls1
i asked the same question when i got my motor. depends on the cam i believe. I had to bump up to 8.1 injectors. they were only 80 bucks on ebay
How big of a cam are you running?
224/224 .561 .561 114lsa
Well damn, I guess I will add that to my list of stuff to buy. It just keeps growing. Come on overtime, I need some money...lol
lol i know the feeling
I really appreciate all the help.
I am going to pick up my motor this week. Im hoping to get the swap done before the end if the month if money allows
You're going to have it done before tomorrow is over?
I got the motor last night. One of the knock sensors os broken. Can I use the one from my 4.8 or do I need to buy a new one for the LS1
they look identical. im pretty sure most of the sensors from your 4.8 will swap over
Cool, Thanks. Looks like its going to be longer before it goes in the truck. I am going to go ahead and replace the oil pump and rod and main bearings before it I do the swap. Cheap insurance and piece of mind
Doing a ls1 swap myself. It will all be worth it in the end. I bought my motor thinking aside from upgrades I was good to go. I also am having to send the block off. Mine was cam bearing didnt look too good. If you are replacing all the other bearing myaswell do it too
stock injectors wont keep up with the LS1
Im going with 8.1 injectors, Still have not decided on a cam thoughQuote:

Its a daily for now so it will get a cam thats good with a 3000 stall. One day it will get a real mans cam and ported heads.
Any suggestions for a cam for now
I stayed with a car intake with my LS1 swap in my ECSB P/U from power plus seems to work well. Real strong mid & upper end & if I lost any lower end I'll deal with it because its shoots off the line plenty hard and thats with my stock stall. Others have had problems with gasket leak. so far I have none but I plan to go to FAST intake soon as I can spot a good used one. I also will be removing my LS1 to replace bearing and upgrading cam and such, now that I found all my bugs on install from 5.3Quote:
