Default 33lb or 36lb injectors for LM7

Ok so i'm gonna get a stage 3 port job on the heads, a 269Lr HR12 comp cam, maybe a different intake, and some wiseco flat top pistons in this 5.3. Does anyone think 36lbs would be overkill?

I'd go with 36lb injectors and just tune for them. That way you'll have a little more room to grow for the future.

Really no such thing as "overkill" with injectors bc you can tune them down as you please. The bigger injector will just allow for more room for growth down the road, if needed.

Only within reason is that true. If your injector is way to big for your application the injector won't be working hard enough to work correctly. It can cause a problem with spray pattern etc.
