Budget LM7 Expected HP gains?

[Yukonjoe2001]

Hello,
Im building my yukon on a budget, It already has a BTR stage 3 truck cam and a cold air intake. Im looking at adding a tbss intake with 36lb injectors, ported 862 heads, and will be installing shorty headers. I know people hate shorty headers, but they were cheap, lighter, look cooler, and do add around 8 HP.. Any estimates on expected HP at the flywheel with this combo?

Biggest bang for the buck is to get a tune from a reputable tuner, none of those canned tunes.
I have the BTR stage 3 cam--plus other mods and I'm getting around 350 at the wheels. That's what really matters imo--at the wheels not at the flywheel.

Btr cams 1 through 4 vs truck norrisWell here is a video to get a basis 400ish at the flywheel. Looks like the stage 3 loses to the stock cam below 2800ish. But gains above that.

I definitely want a dyno tune in the future.. Only problem is i live in northern Michigan, i would have to travel 2-3 hours..lol

Yes, it really comes alive around 3000 rpms

Is it a toy or a daily driver?

Well if you don't have much highway time, 4.56s are always a fun set of gears. But if you have a lot of highway time, 4.11s are probably a good bet.

Thanks.. Ive been considering a factory 4.10 gear.. Lol, for some reason a 4.11 is like $150 more vs a 4.10
