Need advice racing a 380 horse crate engine

My 292/108 didn't even start making power until 5000.
And it liked 7000,same as all the cams I have run,lol
Well maybe not "liked" exactly, but I wound 'em up anyway lol.
Actually I think that cam power peaked at ~5600 IIRC, but that was 18 years ago. So the shift-rpm coulda been as low as 6300 with an A833. Perhaps 6600 with a 727.
But yeah OP's power seems down; it should be going over 100, perhaps as high as 106
I suggest a compression test, to start with
