So I've been collecting some parts for a "budget" 376 build.

First up is a LQ4 block (and crank for the trigger) that's already 30 over I got from a buddy. This was a 408 at one time that didn't last very long. Has fresh cam bearings installed and a pretty clean block for the most part. Going to have it sonic tested to see if I can go another 30 over to fit the LS3 rotating assembly.

4,000 mile LS3 rotating assembly that I'll be using. Everything is in awesome shape and I got a killer deal on it (thanks Mike!).

I'll be running a set of 06' 30k mile 243 heads. Not gonna have anything crazy done to them other than a clean up.

Undecided on the cam yet but my goal is a very streetable 400rwhp through LS6 intake and longtubes.

This will be my first LS I'm assembling myself

 

Very nice! I'm running a 370ci LQ9 myself, and run a cam almost identical to the MS3. Seems to work great with the 5.3 heads, 4.10 gears and 6-speed trans

 

Since very streetable is desired and youll be running stock 243s and ls6 intake, i would say a 228-232 cam with .600 lift on a 114+2 lsa would be ideal.
