Couple questions about the 5.3 swap into f-body
Soon to pull the old motor out and put on my l33 for my gt45 build. Just a few questions that I can't seem to get good answers on. Be on the lookout for the build thread very soon.
- Is the alternator relocation a must?
- Do I need to swap to an ls1 oil pan?
- What size drain for the turbo as I'd like to have it in before the motor is in. I was thinking oil pan so I wouldn't have to worry about hitting balancer or belt? Threading it in ok since I have no way if welding aluminum?

Alright so, i swapped a 4.8 into my fbody. The alternator is a must because it sits to high and will interfere if you are using the stock one from the 5.3. Just use all the accessory and use a manifold that goes over the alternator if using ls1 accesories.
I Dont think the truck pan will fit in an fbody. i swapped from the truck one to an ls1
and i used a -12 to return the oil to the pan

for questions u can swap ur alternator to factory ls1 spot but depending on ur turbo build u may have to re located it again, so see what kit u plan on using and go from there
ls1 oil pan is a yes and i use -10 drain welded (could easily drill and tap also though) to the side of my pan and no issues at all
it will be a fun build, loved mine!

/\ good info, if ur doing a 5.3 swap and ur pulling ur ls1 out, just strip 5.3L to a longblock and swap everything off ur ls1 to it and everything should bolt in no issue, just treat the 5.3 long block like an ls1 long block and u shouldnt have any issues, had my ls1 out and 5.3 in in a weekend with some help from a friend, through the hood too! lol

Thanks for the reply man. As far as the alternator goes, I'm going to fab my own hot and cold sides. I knew to take all the factory accessories off the LS, I seen a swap from CBR performance but really don't want to pay 200$ for for something that I really don't need. Soon to start a thread, I got my Tick cam in today..

Here's a couple pics of it completed also. Need to clean it up a little but you get the idea.

To be your first build, that thing looks great man. Awesome welds and fab work. I been practicing on some tubing and I'm having problems getting decent welds. Just not consistent.
As far as using the oil pan, im guessing that i I can just the windage tray from the l33? Basically just swapping out the pan and dropping the motor in.
You didn't use any flex couplers?
