Add 6,800rpm to my guess

686 CHP

[Sand hauler]

682 corrected hp@ 7200

[WerbyFord]

CORRECTED to STP 60F 29.92 dry sea level, turning water pump only as SAE gross:
2x31 headers
Torq 632 at 4700
Powr 708 at 7000

2.25x31 headers
Torq 632 at 4700
Powr 745 at 7000 +37 wow

UNCORRECTED? Let me hunt down what the un-correction was last time! I agree w Jay/s comments re getting the weather, alt, & air the carb saw going in.
OK it looks like last time the uncorrection factor was about 0.931, SO, uncorrected Gonkulator predictions are
2x31 headers
Torq 589 at 4700
Powr 660 at 7000

2.25 x 31 headers
Torq 589 at 4700
Powr 694 at 7000

What are the header specs?
ok let's go with that, if the CR is really 12.0??? (Turns out I had a good match on the last 392cid at actual CR=11.0!)
Good luck on the dyno!!!

I’ve pushed back the dyno session until the 8th.

Werb, there was a typo last time on the compression ratio.  No typo this time.

Cool! These are fun for everybody, lots of work for you!
Are the headers still 2" primary?

(I know, I found the typo discussion. Sometimes a bad popup design will "act" like a 1.0 CR compression drop, but almost no way to predict that. Glad it was just a typo, the Gonk agrees much better at 11.0 for that 392cid.)

[Stangman]

That 660 looks good for me Werby

[Sand hauler]

Make that 682 uncorrected hp @ 7200 instead

[fastf67]

641 @ 6800
Interesting to see the Trick Flow non ported heads stand with the large cam and intake manifold.
