When does it go on the dyno?
My guess... 396
It's been dyno'd and shipped. It made 390 hp.
I'm just catching up.
Results in dyno section, here:

Torq 458
Powr 390 at 5400
When I Gonkulate it as built in the dyno section (a bit different than above)
Torq 424 at 3600
Powr 387 at 5200
So:
1. This proves to me that the old "not cool" 390HiPo 4v intake is every bit as good as I thought, maybe better.
2. This fits with my 4-intake shootout, where, up to 330ft and 60mph, The 390HiPo intake was the quickest of the 4 intakes I tested on my 4400 lb 3.00 geared dog (390HiPo vs 428PI vs Ed RPM vs Iron-Z)
3. Note the dyno made 34 ftlb more Torq than the Gonkulator. That's some incredible torq from this build.
4. Remember that when this intake came out, USA had not yet put a man in space. In fact IIRC, Ike was still President.
EDIT NOTE: JFK had likely won the election already, but the 390/375-4v is featured in Dec 1960 Hot Rod, so I figure Ike was still in office. Very visionary of Ike to build all those freeways, he must have seen the 1960s cars coming.
