yeah, that's the plan. I haven't had a chance to mock everything up yet; still waiting on pars to arrive.
I've also been wrestling with getting my professional products fuel rail kit to mount properly to the ls3 intake with my stock 28lb injectors.
Not sure if you know but ls3 injectors are a good bit shorted then ls1 injectors. Also I don't think the 28lb injectors are going to supply enough fuel for the 408..
What up, imma stocker? Definately appreciate the info fellas!
My thinking here was to keep my 28lb injectors on while i break in the motor on my previous tune and use my 42lb injectors post break in.
I'd essentially have to get the car tuned twice if I installed the ls3 injectors now, right?
Base tune for break in, then another performance tune.
I'm just going to have a tune done for start up because 408ci, big cam, different maf, intake ect is going to screw with the computer a lot. So I'm going to get a base tune as close as I can for start-up

You'll need a base tune before you fire it up anyways unless previous motor was very similar. A mail order tune will work for that purpose (need to provide build specs so they can get it as close as possible). Ideally the base map will be close enough for break in, then the performance tune after.
Your route might work.... I'd bet you'll blow through several sets of plugs if the motor doesn't get wiped out first.
The plan for tuning would be for me to get an AutoCal to read my PCM calibrations, shoot that info to Pat G so he can modify it and provide me an email tune I can use for break in. I'll data log the car's performance with the new tune and adjust as needed, and take the car to his shop for a full on dyno tune when ready.

Welp, I got a call from G&G telling me I ordered the wrong size piston rings...so that delays the build a bit.
I noticed the inside of my oil pan had a slight crack in it. I'm not sure if it was from me or the previous owner, but I had my pops weld it. I later took a dremel to it to try and smooth out the weld. I'm hoping there won't be any issues.
I picked up the motor today and can't wait to start piecing things together. I did run into a minor issue. They didn't put my crankshaft sprocket/ gear onto the crankshaft. So a couple of questions:
Do I press it on until it bottoms out?
What about the orientation of the dot on the sprocket in relation to the crankshaft?
There are two linear grooves on the snout, what does that mean?
There should be a key way for the sprocket so you can't put it on wrong. You press on crank sprocket until it stops or bottoms out. Make sure you use a key way. I would also fill your oil pan with water and let it sit for a while to make sure you have no leaks.
