Guess the HP

Today we got some testing done, the Dyno is tuned up and working properly
These are the numbers SO FAR....
Peak 637 Ft lbs at 4500 rpm. I think it was making 566 ft lbs at 3000 rpm
Peak 612 hp at 5500 rpm lol.
I'll have some more numbers soon, a graph and a video we're starting tuning now,
Yeah the fenderwell headers are really making it peak early.
The crossover was 5252 rpm 600 for both

Those numbers are with the BLP 850, right? What's the venturi size on that carb?
