Maybe it's just me... but 700 HP at 16 lbs of boost seems a little lower than I would expect for an engine that size with aftermarket heads. Even with a conservative cam.
I've seen similar results on a LS6 crate motor with a small bore BDS 6.:71 with two Holley 650 center squirters on 91 octane CA pump swill back in the early 2000s
That motor had a set of the old TRW forged turbo pistons with a reverse dome(7.5 to 1 comp ratio) and a small hydraulic blower cam, it made 620 HP with 5 lbs. of boost at around 6000 RPM if I'm remembering correctly now. The customer wanted me to JUST check it out initially, physical inspection on the bottom end and a leak down test due to the engine being used out of a street hot rod(1 ton dually Chevy 4 door pickup
) and then he had me dyno test it to make sure it ran and didn't leak. That led to him wanting more power so I bought two more blower pulleys to make more boost and loaned him a set of 850 B.G. Speed Demon carbs I had in stock and swapped the cam to a Comp Cams solid roller set up and put a gear drive on it per his buddy advice
Those changes ended up making right at 780 HP at 6700 RPM with around 12.0 lbs. of boost, the manifold inlet temps went from 130 F with the lower boost to 190 F with the higher boost levels
It did make 700 HP at 7000 RPM with 7.0 lbs. of boost with a smaller blower pulley and his carbs jetted to the best power, he put that motor in a 1972 SS Chevelle he had and he loved it, it would smoke the tires pretty easily according to him
