610hp @ 6200
570tq @ 4600
are you going to test a different carb on it, curious if the annular boosters help the low rpm tq vs a downleg or something...

Me too, I want some numbers to have for gear and converter choice.
Ya know that's a good idea. I'll have to get my other carb ready to do that.

And what do you do when the dyno numbers and the time slip don’t match?

630
Blame the driver is what I'd do
Not enough, never enough and if it is enough now, it won’t be enough tomorrow! Well, that’s how I am at least. LMAO
Your engine looks pretty cool. Best of luck, happy HP hunting!
Looking forward to the results.
OH! Are you going to try a TQ?

Figure out what isn't matched and correct it. This is me in a nutshell. Put my new engine in and hoped the rest would continue to play along, it didn't. I needed a new convertor and gears, mandatory. Also opn the ideal list of changes were carb and headers.

610 TQ at 4,400 rpm
570 HP at 5,600 rpm
I think your HP curve peak will be limited by that small carb. But it will also make the car much more drivable at lower rpm, if this is for a street car.

With 260 @050 on 470 inches with decent heads it should run out pretty good. How far are you comfortable spinning it? It should peak above 6000 and I’ll say it should make more than 600.

I imagine it will be needing more when I get used to it.
I’m the wrong guy to ask that. I’ve seen so many manufactured high horsepower magazine dyno builds that would never be able to prove it on the track.
I really don't wanna push it past 7000, since It took me over 3 years to afford all of this I want to atleast "try" to make it last.
Well it's for race only. I hope you're not right lol.
The blp 850 is supposed to flow over 1000cfm but that was with downleg boosters

My 440, which has [email protected] and 345cfm int heads peaks at 5,900, however I agree it will make more than 600hp, far more.

My experience with the fenderwell headers is they peak pretty early. They improve the numbers below peak TQ, and can show a slight gain in the peak TQ value.
But they didn’t carry the TQ all that well past peak, and as a result...... the HP number suffers.
On the dyno here, with those headers........ I’d be expecting solidly over 600TQ, and maybe 625-635HP...... if the curve hangs on well enough.
Edit- after looking at an old test with a 493 and FW headers, the 625-635hp might be a bit generous.

Pass time was awesome for the overrated underperforming hp cars.
Some of the magazine stuff with 800hp engines in 3200# cars and not even getting 120mph in the 1/4. Yeah, not close to making that power!
Agree with PRH, the fenderwells, especially Hookers will hurt the engine up top. BTDT
That wouldn't be the same guy tuning, would it?
I heard he can be a prick too.
No he's the nice personality lol

My mistake, I thought it was an 850 CFM carb. Well then I'll adjust my total HP guess up to
630 at 6,100 rpm, with the torque still 610 at 4,400 rpm.
Now I think your limiting factor will be the cam duration. You will prably be able to spin it up to 7,000 if you wanted but you will need a bigger cam to make more power at the higher RPM. Nevertheless 1.3 hp per cubic inch is a very respectable amount of power from a 60 year old wedge head design. As Rumblefish360 said it is never enough. And there is always something you can change to get more power.
As for me that is the fun part of a NA engine, searching for that next thing to improve to get more HP. For the turbo guys it is simply a matter of turning up the boost or the NOX guys just bolt on more and bigger injection nozzles (and hope it holds together).
I'm glad to see you are going the NA route, but as you already know, that is the hard way to make power. (but the more satisfying way I think)
The next thing is going to be getting all this power into the track, and chassis tuning can be a new set of challenges. Will you tell us about the car you will be putting this into?
I'll let Tim answer that. lol
