just looking for some advice

OK....ballpark.  300-325  @ 5K RPM flywheel.  You really should take it to a dyno shop and have it dynoed.  There are just too many factors to make a wild guess like I just did.

Get an SCT Chip and find a dealer around you to tune it. 5.0's can be a bear to tune, make sure the tuner you choose is competent.

Numbers, I say in the high 2's at the wheels.

You need a tune though for sure, without a tune your probably not tapping into all that power that you could potentially have. I'm concerned because I didn't see anything about a MAF in your mods list....

its calibrated for the 24 lb injectors

5.0 are not hard to tune, but the best thing to do is go with a tweecer to tune. most aftermarket tuners dont do much more than bump the timing. And that is something you can easily do by advancing the distributor yourself.

We'll agree to disagree. Maybe a H/C/I setup is not really that difficult more than turning a distributor still, but when you start getting into 425+ range on the factory ECM... Trust me it's a lot more than turning the distributor. If you go to a tuner and all he does is turn the distributor, RUN as FAST and as FAR as you can.

I've seen calibrated MAF's be way way off. It's not uncommon to see a "Calibrated" MAF running A/F's in the 10's at idle or the complete opposite running dangerously lean.

If you have a local tuner that does SCT Tuning with the SCT Eliminator Chip, that's what I'd go with.

a tweecer is infinitely adjustable

Yup they do work, Used it before.. Still prefer SCT though.
