Just like when doing a ls swap or engine/turbo all the little things add up fast . Fuel system, injectors, exhaust , driveshaft etc
A few things that I should off done on my original engine build/ls swap
- Go bigger on the fuel pump you will need it . A good 10 micron fuel filter .
- Exhaust system I waisted a lot on my dual 3” mandrel bent system now I’ve changed that up got rid of the h pipe . As I’m single 3” now back to my dual mufflers .
-I had to change my engine mounts to a square body clam shell mount to clear my log manifold
- lots of good cams out there for boost , springs , push rods , lifters and rocker trunnion upgrades are the norm for any engine build
- like short box said drill and tap your oil pan for oil return line . I was lucky my engine sat up high enough to pull pan
- if your running a gm pcm pin a 5 volt wire for your wide band most use the ac volatge pin so wide band will log on the stock ecu
- oil catch can lots of options out there from cheap non baffled cans to nice high end stuff you get what you pay for always
- stall converter depending on cam . I had to swap mine out for a 3200 stall
- rear end gearing I threw in 3:73 and a posi last summer now thinking I should of went with taller gearing for boost
- build your tranny up

Thanks for the Info!
Horsepower looking eventually 650-750. I do have the gen 4 rods and floating pistons. It’s a 2005 avalanche 5.3. It’s kind of a mix of gen 3 and 4. It’s gen 3 block with rear cam sensor and 24x reluctor but gen 4 rods and pistons. I’m not on a super tight budget but I want to get it up and running and I’ll do the boost later.
Planning on gapping the rings. Hopefully there isn’t too much blowup with no boost. Thinking .028 gap.
Planning on BTR stage 1 turbo cam with springs.
Holley terminator x ecu
Maybe ls7 lifters, are new ones needed??
What did you use for a pan?
Probably catch can and 4 corner steam vent.
Still considering trans. I know it needs built up. I always liked t56 magnum but thinking auto now.
