***update***
I got the car dyno'd and there was no HP gain in the peak numbers,... stayed between 261-264rwhp
This manifold however made a drastic improvement in throttle response and drivability. With some supporting mods this might be beneficial upgrade along with tuning.

Had nitrous, so I had spacer plates behind the throttles for the nozzles. I used to pull them to re-jet or just to clean the throttles from time to time.
Car was just exhaust, tune and bottle. But it's gone now.

Wouldn't even say that. That's in the negligible zone. Sounds like this mod doesn't do much as suspected. Maybe with the lowers ported and tuned with mods it would just be another piece to the puzzle.
N/A is a waste of money on these cars, no matter what angle you twist it to. If you are building a track car and are restricted to N/A power then fine, but if you drive on the street, save the thousands on useless mods and either spray the car when you need a real gain or boost the car.
I've run cars with several N/A mods and they aren't appreciably quicker than my car was with just test pipes only.

There's a guy that does all the porting stuff for the 370/g37 forum that has performed the ported upper/matched ported lower and ported tbs. He gained a soling 10 whp/10wtq throughout the power band I'll see if I can find his dyno sheets
